Mushroom scrap spray-drying system

Abstract

The invention dicloses a mushroom scrap spray-drying system, which comprises atomizing equipment, drying equipment and material recovery equipment, wherein a charging pump is communicated with the feeding port of a supercentrifuge atomizer, the discharge port of the supercentrifuge atomizer is communicated with the upper end of a drying tower, and an injection head cooling fan is arranged at the discharge port of the supercentrifuge atomizer; a hot air distributor on the upper part of the drying tower is communicated with a combustion furnace through a settling chamber, and the outlet of the drying tower is communicated with the uppper part of a cyclone separator. By adopting the technical scheme of the invention, spray, drying, dedusting and material recovery are organically integrated, therefore, during mushroom scrap drying process, drying is more thorough, ratio of finished products is improved, and cost is lowered, exhaust emission is nearly zero, environment-friendly advantage is obvious.

Description

technical field [0001] The invention belongs to a spray drying system, in particular to a spray drying system used for drying fungus residues. Background technique [0002] At present, there is no mature drying equipment for the drying of fungus residue on the market. With an ordinary drying tower, the temperature is too low to achieve sufficient drying effect; when the temperature is too high, the static pressure resistance is high, and the resistance that the fan needs to overcome is large, and the wind pressure of the fan is insufficient, and the air volume passing through the finned tube is small, resulting in hot air. The drying capacity of the distributor is insufficient, and the temperature of the hot air distributor remains high, which can easily cause damage to the equipment. At the same time, too high temperature causes the wind speed to have a velocity gradient along the radial direction, which causes air turbulence, reduces the efficiency of the fan, and affects ...

Problems solved by technology

With an ordinary drying tower, the temperature is too low to achieve sufficient drying effect; when the temperature is too high, the static pressure resistance is high, and the resistance that the fan needs to overcome is large, and the wind pressure of the fan is insufficient, and the air volume passing through the finned tube is small, resulting in hot air. The drying capacity of the distributor is insufficient, and the temperature of the hot air distributor remains high, which can easily cause damage to the equipment. At the same time, too high temperature causes the wind speed to have a velocity gradient along the radial direction, which causes air turbulence, reduces the efficiency of the fan, and affects the drying capacity of the drying tower; If the pressure in the tower is too high, it will easily cause blockage, and the bacteria residue cannot be sent to the buffer; if the pressure is too low, the hot air will not be sufficient, resulting in a decrease in the drying rate
