A kind of donkey-hide gelatin drying system and its process

Abstract

The invention discloses a donkey-hide gelatin drying system and a technology thereof. Donkey-hide gelatin is dried through the steps of placing the donkey-hide gelatin subjected to the gel technology and the gelatin cutting technology in a high-voltage electric field for first-stage drying, arranging the donkey-hide gelatin dried through the high-voltage electric field in a wooden case, moving the donkey-hide gelatin into a microwave drying device for second-stage drying, taking samples for testing moisture of the dried donkey-hide gelatin and collecting the donkey-hide gelatin when the moisture of donkey-hide gelatin blocks is smaller than or equal to 15%, wherein intermittent drying is adopted in the drying process. According to the system and the technology, two-stage drying is adopted; through the first-stage drying by the high-voltage electric field, the temperature of the donkey-hide gelatin does not rise, and therefore deformation and bed adhesion possibly caused in the initial drying stage of the high-moisture donkey-hide gelatin blocks are avoided; the later-stage microwave drying is high in efficiency and more uniform. Compared with conventional drying technologies, the technology has the advantages that the drying production cycle is greatly shortened, the efficiency is improved, the cost is lowered, the product quality stability is improved, and the rate of finished products is increased. In addition, the drying system has the advantages that the energy consumption is low, the manufacturing cost is low and equipment is simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of drying systems, and relates to a drying system for donkey-hide gelatin and a process thereof. A sequentially connected two-stage drying method is adopted. The first stage uses a high-voltage electric field drying device to dry donkey-hide gelatin, and the second stage uses a microwave drying device to dry donkey-hide gelatin. . Background technique [0002] Donkey-hide gelatin is a nutritional supplement with high value. The main raw material is donkey skin with different proportions of ingredients. It is processed through various processes such as steaming and cooking. Finally, it is shaped into slices, dried and polished to become the finished product. [0003] After the donkey-hide gelatin is produced, it needs to be dried and shaped, and then it can be sold as a finished product after other processes such as wiping and offset printing. The drying of donkey-hide gelatin is an important link in the whole product...

Problems solved by technology

In addition, in the later stage of drying, when the moisture content of donkey-hide gelatin is low, the moisture migration speed inside the donkey-hide gelatin is very slow, so the drying efficiency of the conventional drying method is very low

Therefore, in the whole drying process of donkey-hide gelatin, a single drying method is difficult to quickly dry donkey-hide gelatin on the premise of ensuring the quality of donkey-hide gelatin.
