Large food processing plants commonly used food freeze drying machine types?

In the process of food processing, according to different food processing technology, a variety of different types of food machinery and equipment will be used, and food lyophilizer is one of the models, so what are the types of food lyophilizer commonly used in large food processing plants? Let's have a look at it.

First, according to production capacity

The types of food lyophilizer can be divided into semi-automatic and automatic types according to the work capacity. The semi-automatic type is mainly used for laboratory research and development of the laboratory lyophilizer, while the automatic type is mainly used for the production of large food lyophilizer types. For example, large food lyophilizer types commonly used 100 square meters, 200 square meters and 300 square meters of food lyophilizer types. And 200 square meters of food freeze-drying machine type is a more widely used food freeze-drying machine type.

Two, according to the food freeze-drying freeze-drying classification

According to their freeze-drying methods, food freeze-drying machines are mainly divided into the following two categories:

1. Pre-frozen food lyophilizer

This type of vacuum lyophilizer uses in situ lyophilization. The shelf of this type of food lyophilizer is equipped with temperature control function. After the fresh food is processed, it is directly put into the lyophilized storage for vacuum freeze drying (temperature control range: -50 to 80 degrees). There is no manual intervention in the pre-freezing and drying stage, which realizes automatic lyophilized processing.

Advantages: Excellent performance and stability of the equipment, long service life, a wide range of freeze drying applications;

Disadvantages: the early equipment cost is higher than the cold storage type, but the low temperature storage and vacuum drying box, the overall cost is not different.

2, cold storage food lyophilizer

This type of food lyophilizer uses low temperature cold storage + vacuum drying box. It is also a traditional food vacuum lyophilizer type. Its working mode is that the pre-freezing and drying stages are separated, and the products need to be pre-frozen by supporting low temperature cold storage, and then manually transferred to the vacuum drying box (temperature control range: normal temperature to 120 degrees) for drying.

Advantages: Shorten the pre-freezing time, low equipment cost;

Disadvantages: shelf plate quality selection of aluminum, can not meet the needs of food processing, drying stage directly heating, product freeze drying effect is general, suitable for some low-end food freeze drying processing.

Through the above introduction, I believe that you have a more in-depth understanding of the common types of food lyophilizer, and we only need to choose the type of food lyophilizer according to the processing requirements of food and the actual processing capacity.
