Drying process of platycodon grandiflorum

Platycodon is a perennial herb with a stem 20 to 120 cm tall, usually glabrous, occasionally densely hairy, unbranched, rarely upper branched. Leaves all whorled, partly whorled to all alternate, sessile or with very short stalks, leaves ovate, ovate-elliptic to lanceolate, leaves ovate or ovate-lanceolate, flowers dark blue or dark purple white, ornamental flowers; Its root can be used as medicine, cough, expectorant, lung, purulent, etc. It is often preserved as pickles in northeast China and used in kimchi on the Korean peninsula. The local ballad "ballad of platycodon" describes the plant. Northeast, north, east and central China provinces and guangdong, guangxi (north), guizhou, southeast yunnan (mengzi, yanshan, wenshan), sichuan (pingwu, liangshan east), shaanxi. Korea, Japan, the far east of Russia and the south of eastern Siberia also have. Root of platycodon grandiflorum can be used as medicine, the curative effect is to promote lung, benefit pharynx, expectorant, discharge pus. For cough sputum, chest tightness, sore throat, hoarseness, lung carbuncle vomit pus, sore abscess. This article briefly introduces platycodon dryer, hope to help the cooperative friends.

Platycodon platycodon seeds two years or transplanting the autumn of the year, when the leaves yellow withered can be dug, cut stem leaves, lu tou, the root soil washed, immersed in water, while fresh with bamboo or glass pieces scrape off the surface rough skin, wash, dry or dry anthracite bed. Now many areas have been using platycodon dryers based on energy-saving and environment-friendly heat pump technology, realizing unmanned, pollution-free, hygienic, efficient and good quality.

Processing steps of platycodon grandiflorum:

1. Put the original crude drug of radix dorsalis on the cleaning table and pick up impurities.

2. Wash and run the selected platycodon platycodon into the medicine washing machine, rinse, wash, then put into the medicine washing pool slightly dipped, remove and smother until thoroughly.

3. Slice platycodon platycodon into 1-2mm slices with a straight cutting machine.

4. Drying put the platter of platycodon platycodon in the drying tray, spread it evenly, put it in the cart, push it into the dryer, and dry.

5. Filter the dried platycodon platycodon tablets into the screen selection machine, screen out the fine particles, the fine particles will be collected separately for storage.

6. Pack the platycodon platycodon in 1kg/ bag, put into the filled certificate of quality and seal.

Characteristics of platycodon dryer：

1, Heat pump dryer set dehumidification, heating, refrigeration, exhaust temperature, ventilation as one of the intelligent equipment, for the new energy-saving emission reduction drying equipment.

2, The use of dual-effect dehumidification technology intermediate heat exchange dehumidification, greatly improve dehumidification performance ratio, energy saving effect is good.

3.Break through the technical bottleneck of traditional dehumidifier and ordinary heat pump dehumidifier: solve the technical problem of poor dehumidification performance or even idling (the operation of the compressor does not remove water) of traditional dehumidifier under the condition of high temperature and low humidity.

4,Unique exhaust air heat recovery design: reduce the emission of heat loss, platycodon dryer comprehensive energy saving is better;

5,Advanced fresh air pre-dehumidification function can ensure fresh air drying, suitable for strict drying process;

6,High temperature heat pump dryer is an environmental protection and energy saving drying equipment, in the drying process will not produce any harmful substances, drying process will not have smoke or open fire, according to the drying material characteristics of temperature and humidity modulation, high intelligence.

7.The drying temperature of platycodon grandiflorum is about 58-62°c, and the drying time is 14-16 hours.
