Processing steps of drying equipment for Chrysanthemum morifolium

- May 03, 2019 -

Introduce the product of Hangzhou White Chrysanthemum Dryer equipment. This equipment is a continuous through-flow drying equipment. It is used for drying flaky, strip and granular materials with good air permeability. It is especially suitable for materials with high moisture content, but not high temperature, such as dehydrated vegetables and Chinese herbal slices. This series of hot air drying equipment has fast drying speed, high evaporation intensity and product quality. The advantages of good quantity are that paste material like dehydrated filter cake can be dried after granulation or rod-like preparation. The working principle of Hangzhou White Chrysanthemum Drying Meter: Material is evenly laid on the mesh by the feeder, and the mesh is made of stainless steel wire mesh. It is driven by a transmission device to move in the hot air dryer. Hot air drying equipment is composed of several units, each unit of hot air circulates independently, part of the exhaust gas is discharged by a special exhaust fan, the exhaust gas is controlled by a regulating valve, hot gas passes through the material laid on the mesh from bottom to top or from top to bottom, heating and drying and taking away moisture. The mesh belt moves slowly, and the running speed can be adjusted freely according to the material temperature. The dried product is continuously dropped into the feeder. Upper and lower cycle units can be flexibly equipped according to user needs, and the number of units can be selected according to needs.

chrysanthemum drying can generally be divided into five steps: picking - swinging flower - baking - picking - packaging, different steps have different requirements.

1. The harvesting season of Chrysanthemum morifolium is the autumn season of each year. It is usually harvested in batches. The total amount of flowers first harvested is 50% - 60%, then 30% every other week, and the remaining batches are harvested every other week. When picking, we should pay attention to the fact that the hearts are mostly scattered, the petals are straight and the color is bright. When picking, attention should be paid to grading according to size and quality. After picking, spread out as soon as possible, let the chrysanthemum lose part of the water naturally, which is more conducive to subsequent drying, and the fragrance will be stronger.

2. Hangzhou chrysanthemum is graded to arrange flowers < / P >

according to the size, quality and grade of the Hangzhou chrysanthemum, laying one layer on the tray [or mesh belt], avoiding overlap and extrusion in the process of arranging flowers to ensure that the petals are on top.

3. The drying of Chrysanthemum morifolium was

After the Chrysanthemum morifolium was laid out, the drying operation was carried out according to different drying processes, and the parameters of temperature, humidity and drying conditions were set up to start drying.

4. After drying, select the Hangzhou Chrysanthemum

Hangzhou Chrysanthemum, after drying, select again and eliminate the bad ones.

5. The packaging and storage of Chrysanthemum morifolium

After picking, the Chrysanthemum morifolium morifolium should be packaged and stored reasonably according to different needs. The dried Chrysanthemum morifolium can not be placed for too long to avoid the second moisture regain. The material in the hopper is evenly laid on the mesh by the feeder. The mesh is usually made of 12-60 mesh stainless steel wire mesh, which is driven by the transmission device to move in the dryer. Hot air drying equipment is composed of several units, each unit of hot air independent cycle, part of the exhaust gas is discharged by a special exhaust fan, each unit of exhaust gas is controlled by a control valve. In the upper circulating unit, the wind from the circulating fan enters the lower chamber of the unit through the side duct, and the air is heated upward through the heater. After distribution by the distributor, the air is blown to the mesh belt as a jet stream, which passes through the material and enters the upper chamber. The drying process is that the hot air flows through the material layer to complete the heat and mass transfer process. The upper chamber is connected by the air duct and the fan inlet. Most of the gas cycle, a part of the lower temperature and higher moisture content of the gas as exhaust gas through the dehumidifier pipe, regulating valve, dehumidifier exhaust. In the lower circulating unit, the air coming from the circulating fan enters the upper chamber first, heates downward through the heat exchanger and enters the lower chamber through the material layer. The lower chamber is connected with the fan by the side air duct and the return air duct. Most of the gas is circulated and part of the air is discharged. Upper and lower cycle units can be flexibly equipped according to user needs, and the number of units can also be selected according to needs.
