The ice cream production line is a complex process that involves multiple steps to transform raw materials into final products. The following is the working principle and main steps of a typical ice cream production line:
1. Raw material preparation
Ingredients: Mix milk, cream, sugar, stabilizers, emulsifiers, and other seasonings (such as vanilla, chocolate, etc.) according to the formula proportions.
Pre mixing: Pre mix all dry ingredients (such as sugar, stabilizers, emulsifiers) first, and then mix them with liquid ingredients (such as milk, cream).
2. Mixing and Heating
Homogenization: The fat balls in the mixture are crushed and evenly distributed by a high-pressure homogenizer, making the texture of the ice cream more delicate.
Pasteurization: Heat the mixture to 70-85 ° C and maintain it for a period of time to kill harmful bacteria while improving the stability of the mixture.
• Cooling: After pasteurization, the mixture is rapidly cooled to 4-8 ° C to prevent microbial growth again.
3. Aging
Aging: Leave the cooled mixture in the refrigerator for a few hours or overnight to allow the emulsifier and stabilizer to fully hydrate, thereby improving the texture and taste of the ice cream.
4. Freezing
• Freezing: Send the aged mixture into a freezer and rapidly freeze it while stirring. During this process, air is stirred into the mixture, forming tiny bubbles that cause the ice cream to expand in volume (usually with an expansion rate of around 100%).
• Temperature control: The temperature during the freezing process is usually controlled between -5 ° C and -6 ° C to ensure that the ice cream reaches the desired consistency.
5. Add auxiliary materials
• Adding accessories: Various accessories such as chocolate chips, nuts, fruit chunks, etc. can be added during or after the freezing process as needed to enhance flavor and taste.
6. Hardening
• Hardening: Put the freshly frozen ice cream into a container and then send it to a low-temperature freezer (usually below -25 ° C) to completely freeze and harden it. This step ensures that the ice cream maintains its shape and texture during transportation and storage.
7. Packaging and Storage
• Packaging: Hardened ice cream can be packaged in cups, barrels, or other forms.
• Storage: Packaged ice cream is stored in a freezer, waiting for transportation and sale.
8. Quality control
• Testing: Throughout the entire production process, multiple quality checks are conducted, including sensory inspection, microbiological testing, and physical and chemical index analysis, to ensure that product quality meets standards.
Modern ice cream production lines are typically equipped with advanced automation control systems that can achieve:
Central monitoring: Real time monitoring of various parameters of the production line, such as temperature, pressure, flow rate, etc., through the SCADA system.
Programmable Logic Controller (PLC): Used to execute specific control logic, such as adjusting refrigeration temperature, controlling stirring speed, etc.
Sensors: Monitor key process parameters such as temperature sensors, pressure sensors, flow meters, etc.
• Automatic Cleaning System (CIP): It can be started regularly or as needed to complete internal cleaning without disassembling the equipment.
• Remote monitoring and maintenance: allow technicians to access the factory network through Internet connection even when they are not on site, and carry out routine inspection or emergency maintenance work.
By combining these steps with an automated control system, the ice cream production line can efficiently and stably produce high-quality ice cream products.

-Formulation:
The ingredients used in ice cream production are: fat;milk solids-non-fat (MSNF);sugar/non-sugar sweetener;emulsifiers/stabilisers;flavouring agents;colouring agents.
-Weighing, measuring and mixing:
Generally speaking, all dry ingredients are weighed, whereas liquid ingredients can be either weighed or proportioned by volumetric meters.
-Homogenisation and pasteurisation:
The ice cream mix flows through a filter to a balance tank and is pumped from there to a plate heat exchanger where it is preheated to 73 - 75deg for homogenisation at 140 - 200 bar, the mix is pasteurised at 83 - 85deg for about 15 seconds then cooled down to 5deg and transferred to an ageing tank.
-Ageing:
The mix must be aged for at least 4 hours at a temperature between 2 to 5degc with continuous gentle agitation. Ageing allows time for the stabiliser to take effect and the fat to crystallise.
-Continuous freezing:
to whip a controlled amount of air into the mix;
to freeze the water content in the mix to a large number of small ice crystals.
-Filling in cups, cones and containers;
-Extrusion of sticks and stickless products;
-Moulding of bars
-Wrapping and packaging
-Hardening and cold storage
