60 to 700 mesh SS304 small oil spice powder making cryogenic
grinder machine
BS cryogenic grinder adopts liquid nitrogen as cooling medium,
which can preserve the material which will not change the original
composition. It can be used for food, plastic, rubber, pharma
industries and so on.
At normal temperature, some sensitive or sticky or elastic
materials cannot be ground to fine powder, even when the grinding
media are running at high speed. But our BS cryogenic grinder
adopts outer media freezing method to grind materials to realize
the heat exchange between material and liquid nitrogen, which can
reach high fineness and won't destroy the nutrition, smell of
material.
Working method:
Our BS cryogenic grinder can use microcomputer control unit for
volume and the amount of nitrogen. Microcomputer is to set
automatic level control system as to customer's requirement,
operators just need to set the expected value of fineness, then the
intelligent control system will automatically adjust the
temperature, the refrigerant valve size, the discharge rate,etc
based on the argument point by the host current,chamber pressure
machine and pipe flow.
Main features:
1) Optimal retention of aroma and strength, in contrast to normal
grinding, where approx.15-43% essential oils are lost, while the
loss with cryogenic grinding isminimal(approx.3-10%).
2) High grinding fineness,low energy consumption, output is 2-3
times than that of normal pulverizer.
3) According to the temperature of material embitterment point,
adjust the best crushingtemperature.
4) Material explosion-proof, anti-oxidation,etc.
5) Trouble-free stable. processing.The machine passes through a
high performance liquid gas gasification unit. In the process of
gasification, the refrigerant and the material produce heat
exchange. And the remaining cool air is collected by means of
reflux.Each part of the use of pipeline valves to adjust the return
air conditioning on the crushing chamber air compensation, material
pre-cooling, closed delivery, closed grading, discharge material
back flow, refrigerant usage, power source mechanism, crushing the
transport process has reached the best results insulation.
