Dairy production line is a kind of liquid food production line, and it can be used as yoghurt production line, ice cream production line, butter production line and cheese production line, and so on. Our dairy production lines are widely used in the production of pure milk, milk beverage, yoghurt, milk powder, ice cream, condensed milk, soy milk and many others. The whole production line has several units:
1. Milk Reception or Powder Dissolving Mixing Section
This unit consists of milk machinery responsible for quality testing, grading, and weighing of the received milk. Storage tanks are available for the storage of the raw materials (fresh milk or powder milk).
This unit is also available for the mixing of milk powder with correct amounts of water. The milk powder can be used in cases where there is a shortage in the quantity of milk or in times of urgency.
2. Mixing and Sugar Melting Section
This unit comprises the following machinery: mixing machine, heat system, cooler, mixing tank or blending tank.
The mixing machine has a heat system that supplies hot water. This machine is used for melting sugar into syrup. A cooler is then used to cool the syrup before it is moved to the next stage, which is the mixing tank/blending tank. In the blending tank, the syrup is mixed with milk, preparing it for pasteurization.
3. Pasteurizer and Homogenizer
In this section, the milk can be further processed by killing the bacteria in order to arrive at the required shelf life.
Pasteurizer
The Pasteurizer carries out two types of heat treatment (Pasteurization). The Pasteurizer is chosen and designed to suit the plant according to the different product types and filling types.
1) High temperature/short time treatment (HTST) - involves passing milk through heated pipes for 15-20 seconds. The temperature is around 72 degrees Celsius. Once this is done, the milk is cooled.
2) Ultra-high temperature treatment (UHT) - the milk is exposed to extremely high temperatures of about 138 degrees Celsius for a short period of time (not more than 2 seconds). This method gives the milk a longer shelf life.
Homogenizer
This milk machinery carries out the task of forcing milk to pass through small holes at a given pressure. This causes the reduction of the fat globules to ensure even suspension. Homogenization improves the quality of the product and a degasser is used to eliminate the air that is mixed with the product.
4. Milk Storage or Yogurt Producing Unit
This is where the product is stored. The unit is also responsible for the production of yogurt.
5. Filling or Packing Unit
This section has packaging machinery which is custom made depending on the type of packaging used. It is beverage machinery designed to carry out the task of mass packaging. The filling types will largely depend on the customers' preference and requirements such as PET bottle, HDPE bottle, glass bottle, gable pack, plastic cups, etc.
6. CIP Cleaning Systems
These are known as cleaning in place systems which are used to ensure that the milk machinery used in milk processing is consistently cleaned and sanitized to ensure high standards of hygiene. They are efficient because they clean the equipment and pipes used without dismantling them. This helps in saving costs while at the same time ensuring that the production line is clean and free of contamination.
7. After Treatment Equipment
After treatment machinery is conveyor, package or pallet, etc.
There are other assistant equipments used such as steam boilers, air compressor, cold water unit, etc.
Installation materials for the product pipes, power pipes as well as electrical installation are provided.
The production line described here is only a sample design. Our company designs production lines in accordance to the customers' requirements. We design and provide whole production lines for milk and juice products called turnkey projects.
Specifications
Capacity of plant: 2T-300T/D.
Products type: 1 or 2 or more kinds.
Filling types can be decided by the customer then designed accordingly.
