Introduction to spices:

  Spices refer to substances that can be used to formulate food flavors and enhance the flavor of foods. Food flavors are generally formulated into food flavors and then used for food flavoring. Some food flavors can also be directly used for food flavoring. The purpose of using food spices and flavors in food is to produce, improve or enhance the flavor of food.
  Spices can be widely used in medium and high-end household seasonings, green foods, health foods, suitable for various soups, cooking, sauces, seasoning sauces, canned food, vegetarian food, convenient snack foods, leisure and puffed foods, nutritious foods, hot pots Industries such as the preparation of soup base materials and so on.

How to dry spices quickly/dehydrate spices in a dehydrator:

  In the process of production and processing of spices, it is necessary to dehydrate and dry the spices, and to realize the dehydrate and dry the spices, it needs to use the dehydrate and dry equipment. Dehydration drying equipment refers to the combination of a series of mechanical equipment to dry the moisture or other liquid on the object by a certain technical means. At present, the popular drying technology has ultraviolet drying, infrared drying, electromagnetic drying, and hot air drying. They have their characteristics and are widely used in various mechanical equipment and food drying.
  Commonly used folk drying methods are:
1. Dry naturally, in the sun or the shade;
2. Hot air drying can be divided into many forms according to the heat source, continuous air supply form, and different equipment;
3. Vacuum drying;
4. Freeze-drying.
  For example, Hot air drying can be selected. The mechanism of the drying process should be mastered during hot air drying. At the initial stage of drying, the moisture on the surface of wet spices evaporates quickly, which becomes the surface gasification stage. When the moisture drops to 10%-15%, the drying speed becomes slow. In the drying process, the coordination of the internal and external diffusion of moisture is quite important. If in the drying initial stage, the outer diffusion of moisture exceeds the inner diffusion, the spice surface layer becomes hard, not only hinder the continued evaporation of moisture but also delay the speed of drying. Therefore, drying to regularly turn and control a certain temperature. High temperature is easy to make the raw material in the aromatic and spicy components volatilization and cause the loss of other organic matter, so that the product turns brown, char taste, affect the appearance. If the temperature is too low, the drying time is too long, which affects the production efficiency, often aggravating microbial pollution and affecting sterilization.
   Therefore, choose what kind of dry method, should look at the climatic condition of the place and decide, be in commonly 25-30 degrees the good method that dry from heat shade is to prevent essential oil loss, and the infrared ray illuminating method that gives newly recently is a good technology of dry fragrant plant. In addition, the most environmental protection method of drying, dry heating stage of drying and cooling stage, this is by nitrogen gas heating spices, after the compression of high pressure on the physical, cooling and condensation, and to realize the spices flavor substances in drying process no oxidation, essential oils, no loss, low moisture after drying, dry sterile and safe environment.

The principle of spices dryer machine working:

  Baixin air energy heat pump dryer uses the reverse Carnot principle. The refrigerant is compressed by the compressor to become high-temperature and high-pressure gas, enters into the heat exchanger through the pipeline, and then passes through the fan to remove the heat generated by the heat exchanger send it to the drying room to heat and dry the seafood products and other materials, so that the seafood products are dried, and the moisture is discharged from the moisture outlet. The dehumidification system has a heat recovery device, and the recovered heat is used to heat the fresh air, which can save 60%-70% of the fresh air preheating energy consumption.
