Drying tips: Different drying materials have different drying processes.

 Different drying materials have different drying processes.

There are many types of drying materials, and the drying processes are also different. Common types of materials include flowers and leaves, roots, aquatic products, meat, fruits, etc. Removing moisture is only the first step in drying materials, and more importantly. It is to ensure the drying quality of materials. Let me introduce to you the key points of drying different types of materials.

Flower and leaf materials usually have high requirements on the appearance and quality of the finished product, so the focus of drying is on color fixation and moisture control. Therefore, the temperature cannot be too high and the dehydration speed cannot be too fast.

It is difficult to remove moisture from rhizome materials, so the key point of drying is to balance dehydration. While ensuring that the materials meet the drying requirements, the quality and appearance of the materials must also be ensured. This needs to be determined according to the internal structure and air duct of the drying room. Some materials need to be dried multiple times. If moisture accumulates, sweat will form and drip on the surface of the material, causing the material to turn black.

The drying cycle of aquatic products is long and is generally required to be carried out at a relatively low temperature to avoid high temperatures affecting the drying quality of the product. In addition, aquatic products generally have a large moisture content, so controlling moisture removal is an important factor in determining drying quality.

Most meat materials have a large amount of dehydration, a large number of drying quantities, and are prone to spoilage. The key points of drying are to inhibit bacteria and balance dehydration. Typical materials include bacon, sausages, salted duck, etc.

Fruits usually have the characteristics of polysaccharide and slow water release, so the temperature, humidity and time need to be strictly controlled and cannot be rushed. Fruity materials need to pay special attention to the saccharification effect during the drying process. Too high a temperature and too fast a dehydration speed will cause the material to turn black.After mastering the material drying process, it is also important to choose good drying equipment. Western Daqi drying equipment is energy-saving and environmentally friendly. You can choose natural gas, steam, electricity, biomass particles, air energy, coal or firewood as heat sources. It can be customized according to the drying needs of the materials.
