Vacuum freeze dryer is suitable for drying high-end raw materials such as pharmaceuticals, traditional Chinese medicine decoction pieces, biological and wild vegetables, dehydrated vegetables, food, fruits, chemicals, pharmaceutical intermediates, etc. Freeze vacuum drying is a new type of box structure developed by combining the refrigeration system, vacuum system, thermal oil heating system, and dehumidification system in a vacuum freeze dryer, which greatly utilizes the storage space inside the box for freeze-drying.

1. Working principle and application industry
Cone spiral belt vacuum dryer is a common and important industrial equipment widely used in chemical, pharmaceutical, food and other fields.
Its main function is to quickly remove moisture from materials by vacuum drying them at low temperatures, ensuring product quality and stability.
1). working principle
The conical spiral belt vacuum dryer adopts a unique design and working principle.
It mainly consists of a conical container, a spiral stirrer, a vacuum system, a heating system, and a cooling system.
Firstly, add the wet material into the conical container through the feeding port.
Then, the spiral mixer starts to operate, evenly stirring and mixing the materials.
Then, the vacuum system starts working, extracting the air from the container to create a vacuum environment.
At the same time, the heating system heats the conical container by heating the external medium.

The hot air circulation oven is used for heating, solidification, drying and dehydration of materials in industries such as pharmaceuticals, chemicals, food, agricultural and sideline products, aquatic products, and light industry. Such as raw materials, traditional Chinese medicine slices, extracts, powders, granules, dehydrated vegetables, etc.

Descriptions:

This drying machine is suitable for drying the material and product hot solidification and dry de-watering in pharmaceutical, chemical, food, farming, byproduct, aquatic product, light industries, heavy industries and others industries, such as medicinal raw material, Chinese traditional herbal medicine, plaster, powder, particle, drinking agent, pill, packing bottle, pigment, dyestuff, de-watering vegetable, dried fruit piece, sausage, plastics, resin, electric component, baking varnish and more

The hot air oven is suitable for baking items with chemical gases and food processing to be baked, curing ink, drying paint films, etc. It is widely used in precision baking, drying, tempering, preheating, shaping, processing, etc. in electronics, motors, communications, electroplating, plastics, hardware and chemical industry, instruments, printing, pharmaceuticals, PC boards, powders, immersion, spraying, glass, wooden building materials, etc; Internal heat circulation ensures even heating of baked goods.

Food freeze-drying machine is a machine that freezes food and evaporates ice water under vacuum to prepare freeze-dried food. It can make various types of food, such as freeze-dried fruits, vegetables, meat, seafood, and food mixtures.
Freeze dried food is a type of food that has undergone freezing and vacuum treatment. It is obtained by freezing food at low temperatures and then evaporating ice water under vacuum, causing the food to lose moisture and become dry. Freeze dried foods do not require the addition of chemical preservatives or other additives to maintain their freshness, so they are usually healthier and more nutritious.

Product Description

Applications

Vacuum freeze drying technology is currently worldwide most advanced technology for food dehydration processing. Compared with the commonly used drying method, the freeze-dried food produced with this technology features long period of quality assurance, good re-hydration nature, good-looking color, good flavor, taste and high content of nutritious components. The dried food basically remains unchanged in its volume and shape, looks like sponge and has no shrinking. This drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, medicine, beverage and etc.

Freeze drying machines are widely used in fields such as food processing, drug manufacturing, and biological research. In terms of food processing, freeze-drying machines are commonly used in the production of freeze-dried fruits and vegetables, meat products, dairy products, coffee, and tea. In the field of pharmaceutical manufacturing, freeze-drying machines are used to prepare products such as inactivated vaccines, biologics, and drug injections. In addition, freeze-drying technology can also be used to preserve rare plant seeds, prepare microbial cultures, and manufacture cosmetics

Freeze dryer is a device that utilizes the sublimation principle to freeze water containing substances at low temperatures, and then directly sublimates solid ice into gas in a vacuum environment for removal. This type of equipment can obtain freeze-dried substances with very low water content and rehydration properties. The stability of the materials can be enhanced through freeze-drying equipment processing, which can preserve the substances for a long time and prevent the physical, chemical, and biological denaturation of dried substances.
