No one knows exactly when ice cream was first produced. Ancient manuscripts tell us that the Chinese liked a frozen product made by mixing fruit juices with snow — what we now call water ice.
This technique later spread to ancient Greece and Rome, where the wealthy in particular were partial to frozen desserts. After disappearing for several centuries, ice cream in various forms reappeared in Italy in the Middle Ages, most probably as a result of Marco Polo returning to Italy in after some 17 years in China, where he had acquired a liking for a frozen dessert based on milk.
From Italy, ice cream spread through Europe during the 17th century, long remaining a luxury product for the royal courts. Industrial ice cream production began at the end of the 19th century when the first mechanical refrigerators were pioneered. Ice cream and related products can be divided into a number of categories. As legislation varies from one country to another, the following should be regarded as a guideline only.
The fat content of ice cream typically determines the category to which it belongs. The fat can be either of animal or vegetable origin. If the latter, legislation in a number of countries dictates that the product cannot then be called ice cream, but must be labelled, for example, non-dairy ice cream or frozen dessert. Sorbet is the term used for a frozen, typically fruit juice-based product with a certain amount of overrun.
The mix passes through a continuous freezer where air is incorporated. Sorbet products are characterized by fresh eating properties and do not contain fat or milk solids-non-fat MSNF. Due to the higher viscosity from the freezers, fruit pieces and other inclusions can also be added to the sorbet product before filling. Sherbet still retains the fresh eating properties associated with sorbet. Frozen yoghurt gained enormous popularity in the US during the s due to its relatively low fat and calorie content.
Weight and cholesterol watchers were delighted. Typically, a frozen yoghurt is a blend of standard ice cream mix and yoghurt with live bacteria, yoghurt ice cream tends to have a fresher taste than standard ice cream. Today also Greek yoghurt is popular due to the high protein content. Water ice is a blend of sugar, fruit concentrates, stabilizers, flavour and colour.
The finished mix is pasteurized and mostly filled into moulds or pockets on a rotary or in-line moulding machine. Freezing takes place in the pockets, which pass through a cold brine salt solution freezing zone. When the water ice is frozen , it is extracted from the pocket.
Combinations together with an ice cream core also make the products appealing for adults. The development of extrusion technology has created a new category known as extruded water ice.
Basically, a water ice containing a whipping agent is pumped to the continuous freezer, where air incorporation and a significant part of the freezing of water takes place in the continuous freezer cylinder before extrusion. Ice cream or water ice mix is filled into moulds and frozen to produce stick novelties.
After extraction, the products can be dipped in chocolate or other coatings. Ice cream is typically extruded onto a tray by means of extrusion with a cutter. A wide variety of products can be produced including stick novelties, sandwiches, desserts, ball-top cones and so on. Extrusion technology provides the possibility to work with ice cream drawn at much lower temperature where the viscosity of the ice cream is high due to more water being frozen into ice crystals.
This generates ice creams that are both smoother due to smaller ice crystals and creamier due to higher churning of fat compared to moulding and filling technologies. The higher viscosity also offers the possibility to work with detailed forms and flavours, decorations and coatings.
Zoom Fig. The manner in which raw materials and ingredients are received varies from one factory to another depending on its facilities and capacity. Dry products are usually delivered in bags.
Bulk materials such as sugar and milk powder can be delivered in containers and blown into storage silos using compressed air. Liquid products are often delivered in tankers. The fat gives creaminess and improves melting resistance by stabilising the air cell structure of the ice cream. Milk fat is used in the form of whole milk, cream, butter or anhydrous milk fat AMF.
Milk fat can be replaced by vegetable fat, where refined or hydrogenated hardened coconut oil and palm kernel oil are most commonly used. The use of vegetable fat in ice cream is regulated by legislation in many countries. In addition to its high nutritional value, MSNF helps to stabilize the structure of ice cream due to its water-binding and emulsifying effect. The same effect also has a positive influence on air distribution in the ice cream during the freezing process, leading to improved body and creaminess.
In a well-balanced recipe, the quantity of MSNF should always be in proportion to the water content. The optimal level is 17 parts MSNF to parts water:. Zoom Formula Sugar is added to increase the solids content of the ice cream and give it the level of sweetness consumers prefer.
Sugar is the common description for the saccharides, including the monosaccharides i. The consistency of the ice cream can also be adjusted by selecting different types of sugar. This makes it possible to produce ice cream that is easy to scoop. In the production of sugar-free ice cream, sweeteners are used to replace sugar.
Aspartame, acesulfame K and sucralose are the most commonly used sweeteners in ice cream and are applied in conjuction with a bulking agent such as malto-dextrin, poly-dextrose, sorbitol, lactitol, glycerol or other sugar alcohols. Emulsifiers and stabilizers are typically used as combined products at dosages of 0. Traditionally, these products were produced by dry blending, but today integrated products are preferred due to the improved dispersion and high storage stability.
Emulsifiers are substances that assist emulsification by reducing surface tension between two phases. Egg yolk is a well-known emulsifier, but is expensive and less effective than the most commonly used types. A stabilizer is a substance that has the ability to bind water when dispersed in a liquid phase.
This is called hydration and means the stabilizer forms a matrix that prevents the water molecules from moving freely. Stabilizers are used in ice cream production to increase the viscosity of the mix and create body and texture.
They also control the growth of ice crystals and improve melting resistance. The most popular flavours are vanilla, chocolate and strawberry. In the EU, flavours are classified in three groups: natural, nature-identical and artificial. Nature-identical flavours are the most commonly used. Natural or artificial colours are added to the mix to give the ice cream an attractive appearance. Local legislation exists in most countries regarding the use of colours in food. Many moulded and extruded ice cream products are coated with chocolate.
Two types of chocolate coatings are used: real chocolate and chocolate compound. The cocoa mass and butter are replaced with a blend of cocoa powder and vegetable fat in the chocolate compound.
Ripples sauces are incorporated in ice cream for taste and appearance. They can also be applied for pencil filling and top decoration. Dry ingredients are either added through an ingredient doser or as top decoration matter on cones, cups and bars. A great variety of products are used: chocolate, nuts, dried fruit pieces, candies, cookies, Smarties, caramel pieces, etc. The mix composition and resulting ice cream are illustrated in Figure The tank-stored raw materials are heated and blended to form a homogenous mix that is pasteurized and homogenized.
Large production plants often have two mix tanks for each flavour with a volume corresponding to the hourly capacity of the pasteurizer, in order to maintain a continuous flow to the freezers. The dry ingredients, especially the milk powder, are generally added via a mixing unit, through which water is circulated, creating an ejector effect that sucks the powder into the flow.
Liquid ingredients such as milk, cream, liquid sugar, etc. In large-scale production the ice cream mix flows through a filter to a balance tank. The purpose of pasteurization is to destroy bacteria and dissolve additives and ingredients.
The homogenization process results in uniformly small fat globules which improves the whipping property and texture of the ice cream mix. Ageing allows the milk proteins and water to interact and the liquid fat to crystallize. This results in better air incorporation and improved melting resistance. The ice cream mix is metered into the freezing cylinder by a gear pump.
At the same time, a constant airflow is fed into the cylinder and whipped into the mix by a dasher. Figure The refrigerant surrounding the cylinder generates the freezing process. The layer of frozen mix on the inside cylinder wall is continuously scraped off by the rotating dasher knife, and a second gear pump drives the ice cream forward either to an ingredient feeder or a filling machine. The ice cream bar in figure Here the large air bubbles are covered with the crystallized fat globules that supports the air bubble structure.
The unfrozen phase surrounding the air bubbles contains a freeze-concentrated mix of sugars, dairy solids and stabilizers. The unfrozen phase also contains the ice crystals.
The function of the ingredient doser, Figure The pump is designed to ensure the ingredients are gently fed into the ice cream flow from the freezer. The ingredient doser is designed to handle all three kinds of ingredient. Dosing accuracy is controlled by the use of ingredient-weighing cells under the ingredient hopper. A filling machine fills ice cream, sorbet and water ice directly from the freezer into cups, cones and containers of varying design, shape and size.
Filling takes place by means of a time-lapse filler, a volumetric filler or an extrusion filler.

Many production managers have de-stocked excessively large inventories, gone lean, experimented with continuous improvement processes and introduced new working practices. These interventions have largely failed. Businesses have also failed to invest in the workforce that undertakes improvements. This means that cash flow stops quickly, stocks are depleted to zero and customers lose confidence. Systems for Manufacturing Excellence looks at how people and technology work effectively together to generate high performance manufacturing and service operations. Not everyone is a Toyota but that does not mean we cannot learn from such businesses. The book will present a logic, variety of approaches and methods that underpin the different models of high performance used by 'world class' businesses.

One of the most common service calls we receive is customers informing us that their ice maker is not making as much ice as it used to. Although an uptick in business sounds like a good problem to have, it also means that your current model needs to be able to keep up with the influx of new customers. For example, a pound ice machine may have produced enough ice when you first opened, but more customers mean more ice demand. For instance, a KM produces roughly pounds of ice while consistently running under ideal temperatures of degree ambient air and degree water. This trade association represents more than manufacturers of AC, heating, refrigeration equipment including ice machines. The AHRI rating measures the amount of ice your machine is likely to produce under more realistic temperatures.

When considering the manufacture of ice on board fishing vessels, seawater will be the natural choice of raw material. When considering whether to use fresh or seawater in land-based plants, the decision will depend on several factors, such as the availability of regular supplies, the location of the ice plant and the intended use of the ice e. Whatever type of water is used, it must be remembered that the resultant ice will come into direct contact with food. For this reason it is essential that the water used is free from contamination that could cause risks to human health or tainting of the fish so that it becomes unacceptable. This implies that the water must be of drinking-water quality and comply with the safety standards laid down by such bodies as the World Health Organization. The use of seawater ice for chilling fish has been studied for several years and, with the development of suitable small ice machines that can be installed on board fishing vessels, this alternative is becoming more feasible for fishermen. The main advantages of the use of seawater ice are:.
