Processing Technology of Ganoderma lucidum Powder

Processing technology, generally using direct grinding or extract drying into powder. Direct grinding will first crush the fruiting body of Ganoderma lucidum into small pieces, and then grind it repeatedly with electric mill and sift it to get fine powder. The extract is dried into powder, and the fruiting body of Ganoderma lucidum is crushed first, and then soaked in warm water. The extract is then dried into powder. This kind of fine powder does not contain cellulose, the commodity value is higher, and the market prospect is better. This processing method is described in detail below.

1. The dry Ganoderma lucidum fruiting body without dust and mildew is selected for the preparation work, and the equipment includes grinder, sandwich reaction tank, vacuum film concentrator and spray dryer.

2. The preparation of the concentrated liquid of Ganoderma lucidum the fruiting body of Ganoderma lucidum was washed, crushed and boiled in a sandwich reaction tank with appropriate amount of water. Keep at 100 degrees for 2 hours, then squeeze out the liquid, combine the extract repeatedly for 3 times, filter, and get the filtrate. Then the filtrate is introduced into the vacuum film concentrator to concentrate the liquid to more than 10 Baume degrees and set aside.

3. The fine powder of Ganoderma lucidum is made by the function of fine powder. Spray drying method: the concentrated liquid of Ganoderma lucidum and a certain proportion of filler were evenly stirred and then introduced into the spray dryer and dried into powder. The temperature of the input gas of the spray dryer is controlled at 95 Mel 100%, and the nozzle pressure is maintained at 3.5 Mel 4 standard pressures; the temperature of the exhaust gas is 95 degrees, and the temperature error is less than ±2 degrees.

4. Packaging of Ganoderma lucidum Powder the Ganoderma lucidum powder is sealed and packed in colored food plastic bags or special glass bottles to prevent damp and mildew.

5. In the process of crushing, the size of Ganoderma lucidum particles should be uniform and moderate, the solids are not easy to dissolve if the particles are too large, and the extraction rate will be affected if the particles are too small and the filtration is not smooth.

6. The effective factor content of Ganoderma lucidum concentrate during spray drying directly affects the quality of Ganoderma lucidum powder. The practice shows that the content of solids in the extract is 11mur13 Baume, which is the best concentration of spray drying, and the quality and color of Ganoderma lucidum powder are excellent.

7. In the process of spray drying, the flow rate per unit time of concentration is inversely proportional to the temperature in the tank. Therefore, the liquid flow is too small, the temperature changes, easy to coke powder; liquid flow is too large, temperature drop, easy to stick to the wall phenomenon and difficult to form powder. Therefore, special attention should be paid to the changes of liquid volume and temperature in the operation, and should be adjusted at any time.
