low price freeze drying equipment

Descriptions of drying equipment:

1.This food lyophilizer is used to produce health care products, luxury food, and other high value-added products.

2.Its vacuum system is made of vacuum pump or roots pump. Its main function is to form a vacuum environment and pump out the air. The admission port of each vacuum pump all have a automatic stop valve that can prevent the return flow of air caused by power failure.

3.The cooling system is made of cooling compressor, water cooling condenser, expanding valve, plate-type evaporator, and oil content. Each imported stand-alone two-stage semi-closed compressor can constitute independent refrigeration cycle system to cool the plate layer and cold trap through plate heat exchanger or condenser pipe.

4.The main pipeline of the system is advance and accurate enough to operate effectively for a long time.

5.The cooling system has enough cool capacity that can be answerable for the water vapor load produced by sublimation. It is also equipped with motor overload thermal protection, high pressure protection, low pressure protection, medium pressure protection, hydraulic differential protection, automatic liquid collection, cooling water shortage protection, and other various functions.

6.The compressor also has a CPCE pressure regulator that can prevent the compressor from running in the extreme working conditions and keep the secondary compression ratio in balance.

7.The circulatory system is to use circulating pump to force the refrigerating medium to circulate. The purpose is to ensure the cold heat exchange between refrigerant and secondary refrigerant, secondary refrigerant and plate layer, plate layer and products.

8.Cold trap is the device to collect the sublimated water vapor. It is connected with the dry container, which is separated by mushroom valve or butterfly valve to make the material feeding and frost happen simultaneously. When entering into the discrimination program after freeze-drying, it will automatically carry out pressure experiment to find out the freeze-dried end points. In case of short time power outages (10min), the butterfly will automatically close and using the pressure difference between cold trap and drying oven to keep the sublimation state to ensure the safety of the products.

9.Plate layer is the direct component to freeze and sublimate the products. The plate layer is grouped by attachment frame.

10.The dry container is designed according to vacuum container design and manufacture standard. Its interior is processed by rounded technology, and the slope bottom is in favor of CIP water draining. The door is sealed by O cross section rubber and the side is equipped with lampshade lens.

Main features of drying equipment:

1.It can be used to produce meat, vegetables, fruits, aquatic products, soy milk, drinks, soup, and health care products. The food it produced is natural, nutrient, and convenient.

2.This kind of freeze drying equipment is developed based on our accumulative experience and absorbed the similar equipment leading technology in the world. It uses built-in alternate working steam trap, full liquid circulation cooling system, heating and steam trap system designed on the sublimation accelerating theory, and negative pressure steam melt advanced technology.

3.It can keep the original color, aroma, taste, shape, vitamin and protein of the products. It is natural without any antiseptic substance and it has an excellent fresh keeping ability.

4.The products it produced have very long shelf life and corresponding shelf period under the condition of good packaging. It can be preserved at normal temperature, thus it won’t need any cold storage or refrigerated conveyance.

5.The products can be stored in low temperature display cabinets and household refrigerator. Because most water of the material has been removed, the products are light and convenient for transportation.

6.The products have fast rehydration speed and are convenient to eat. This equipment will have high additional value and economic benefits.

Functions of drying equipment:

  This type freeze dryer conforms to sanitary requirement. It can maintain biological activity, color, flavor and aroma, decrease the loss of volatile substance and thermosensitive substance, and keep the original properties to the largest extent. The products it dried have good reconstitution properties, oxidation resistance, and long storage life, and their volume and shape remain the same.
