1-INTRODUCTION
In this paper we aim to provide an overview of the manufacturing process of an ice cream plant in Nicaragua, the Eskimo.
Can be defined in the ice cream as a sweet-tasting food from a mixture of pasteurized and various ingredients (milk, water, sugar, cream, juices, eggs, cocoa, etc.), which is whipped and frozen for later consumption different shapes and sizes. Generally in the manufacture of ice cream are used various special additives such as thickeners, colorings, flavorings and stabilizers. When a food is the mixture of various components can present various physical structures within an overall appearance. In the case of ice cream, its structure may seem typically strong when they are well frozen, can have a pasty, semi, when they are near their melting point, or can be liquid melt if left at room temperature. Inside the ice cream can live almost all types of physical structure. As the iced the outcome of the union of a series of solid and liquid ingredients, the type of union can be very different.

2.1.-Equipment
Mixture, homogenization and pasteurization
For the production of ice cream mixture has chosen a processing plant mixture (mixture HTST Hoyer, the trademark or similar Hoyer Tetra Pack) that includes the mixture itself, homogenization and pasteurization at high temperature (HTST: High Temperature Short Time). The pasteurization takes place in a heat exchanger at a temperature of 84 º C for a short time (25 seconds). This produces a continuous flow of ice cream mixture.
The processing plant mixture Hoyer HTST mix is available in standard capacity of 600, 1200 and 2000 liters / hour. Since the desired output is 953 liters per hour, you choose the model of 1200 liters / hour to better adapt to the needs.
The processing plant mixture Hoyer HTST mixture is characterized by its compact design of stainless steel. All components are placed on a rack, which facilitates the installation and takes up minimal space. The Calderín is located in a separate chassis, so it can be placed near or far from the plant mixture. The plant consists of standard:
. A Calderín to provide hot water tanks mixture through a pump. The standard Calderín is heated by steam.
. A feeder powder products to add ingredients into powder to the tank mix.
. Two mixing tanks, where the liquid ingredients are driven, while the solid ingredients are added through the feeder powder products. The tanks are fitted with agitators.
. A centrifugal pump to send the mixture to the tank of regulation.
. A tank of regulation with the float, complete with two filters and a system of by-pass.
. A centrifugal pump to send the mixture to heat exchanger plates and homogenizing.
. An exchanger plates of 5 sections to heat, cool and pasteurized.
. A homogenizing to homogenize the mixture to the pressure of more than 200 bars. The homogenizing is equipped with a filter made of stainless steel.
. A section of keeping the mixture at a temperature of pasteurization for 25 seconds.
Features:
. Dimensions: 6300 mm1750 mm2000 mm
. Power consumption: 16 kW.
. Capacity: 1,200 liters / hour.
Melting butter
To melt the butter necessary for the production of ice cream will be available Pump Station Multi Multi Hoystat of the trademark or similar Hoyer.
The pumping station Hoystat Multi is an independent unit equipped with a tank, a pumping system and a control panel. The reservoir has a capacity of 150 liters and wears a shirt by circulating steam. The warming of the butter is fast and a thermostat ensures a proper temperature control. The pump is a positive displacement pump. It has agitator with a scraper to better melt the butter.
The unit is constructed entirely of stainless steel, providing an easy and efficient cleaning.
The control panel is located on the front of the tank and has controls for dosing the amount of steam entering and leaving the butter, as well as their temperatures.
Features:
.Dimensions: 11558351212 mm
. Pump capacity: 10-900 liters / hour
