Freeze-dried coffee is instant coffee that converts coffee extract into solid particles through freeze-drying technology, which can better preserve the flavor and aroma of coffee. The process flow is as follows: Coffee extraction: After the roasted coffee beans are ground, they are extracted with hot water under high pressure to obtain a high-concentration coffee liquid.

I、 Production process 1.Core process: ‌1.1 Raw material processing: Select apples without pesticide residues (such as Lijun Ecological Farm products), wash, peel, core and cut into pieces, and protect the color in an antioxidant solution (vitamin C or tea polyphenols) to prevent browning. 1.2 Pre-freezing and freeze-drying: Place the apple pieces in a vacuum freeze dryer

Freeze-dried bird’s nests are pre-frozen in the bird’s nest at minus 40°C using a food freeze dryer, and then the solid water is sublimated under a vacuum environment to achieve an absolute moisture content of less than 5%, leaving the original structure of the bird’s nest intact. It effectively avoids the thermal loss of sialic

The food freeze dryer freezes the water in the material into a solid by cooling it down, and then sublimates the solid water ice into water vapor directly by reducing the vacuum and gently heating it to achieve the purpose of dehydration. Compared with the dehydration method of heating and drying, freeze drying has many

In modern biopharmaceuticals, food processing, chemical experiments and other fields, freeze dryers are indispensable equipment. It removes moisture from solid samples through freezing and vacuum technology to ensure the long-term preservation and stability of the product. But every device has its performance limitations, and freeze dryers are no exception. The upper drying limit of a

  The application range of royal jelly freeze-drying process is very wide. It can be used to make royal jelly capsules, royal jelly oral liquid, royal jelly health products and other products. At the same time, due to its high stability and safety, it is also widely used in medical, health care and other fields.

1. Raw materials: fresh beef shank meat, which meets relevant standards and is roughly the same age. 2. Pretreatment: Remove the tendon, fat and other impurities from the beef, wash it under running water, cut it into pieces of about 250g, put it in a pot under cold water at room temperature, insert a toothpick
