Pore ​​A material, or more or less empty voids in a system, where a particularly large void is called a cavern, a particularly finely defined molecular void, and a gap between the two is called a void. It can be seen that the so-called pore is a qualitative concept. The pores in a porous medium may not be in communication with each other, but it is certain that at least some of the pores are in communication, and the connected portions are generally tortuous rather than linear. Porosity (e) The ratio of the volume of the pore to the total volume of the system, ie e= Effective porosity (e- effect ) The ratio of the interconnected pore volume in the system to the total volume of the system, ie e effect = Specific internal surface area (S table ) The ratio of the surface area to the external surface area of ​​the system. The pore size of the pore (d hole ) is artificial, not real, numerically d hole = Distortion (T- curve ) The ratio of the actual flow length of a fluid to the linear distance from the inflow to the outflow. It is a dimensionless scalar.
Plastic Basket Washing Basket Cleaning Machine:
After the washing machine is turned on, it is manually fed to the spray cleaning machine chain track or automatically fed by the conveying connection. First, the alkali liquid is sprayed, then the hot water is sprayed, and then the water is sprayed by the circulating water to spray the disinfectant. The four groups are independent, external circulating water tanks, and the filter net can be easily extracted. The turnover box flushes the inlet and outlet by manual operation.
Bubble spray cleaning machine: It is especially suitable for cleaning delicate fruits and vegetables, jujubes, dates, golden jujubes, apples, oranges, ginger and other foods with many impurities and difficult to remove. It can be used with hair rollers, sieve plates and mesh belts. The washing machine is used in combination.
We also manufacture: meat processing machines, milk processing machines, egg processing machines, fruit vegetable machines etc. We have years of exporting experiences, sincerely hope for copperation!

Mesh belt bubble cleaning machine: used for all kinds of fresh vegetables, salted vegetables, fungi, and seafood. The cleaning machine adds a spray cleaning function during the material conveying process, so that after the material is cleaned in the steam bath, it is sprayed and cleaned. The function of this process is to replace and remove the dirty water on the surface of the material to improve the cleaning of the material effect.
We also produce brush cleaning machines, conveying equipment, hoists, vibrating air dryers and dryers.
