A kind of mycelia drying method

Abstract

The invention discloses a method for drying mycelia. The method includes the following steps that (1) initial mycelia with the water content of 75%-80% are fed into a distributing bin of microwave hot air composite drying equipment to be mechanically distributed; (2) the distributed mycelia are conveyed into a drying chamber of the microwave hot air composite drying equipment and dried through hot air and microwaves at the same time, and meanwhile moisture in the drying chamber is exhausted through a dehumidifier; after being dried to be with the water content of 20%-25%, the mycelia are discharged, and the discharge temperature is 80-90 DEG C; (3) the mycelia are fed into the drying chamber of the hot air drying equipment to be dried, and meanwhile moisture in the drying chamber is exhausted through the dehumidifier; when dried to be with water content lower than 10%, the mycelia are discharged, and the discharge temperature is 60-70 DEG C; (4) the mycelia are smashed, screened and graded; and (5) materials of different grades are inspected and packaged, and dried finished mycelium are obtained. The process is short in drying period, simple in procedure, high in efficiency and free of pollution.

Description

technical field [0001] The invention belongs to the field of drying methods, and in particular relates to a mycelia drying method. Background technique [0002] In the process of producing antibiotics by industrial microbial fermentation, a large amount of mycelial residue will be produced after the antibiotic is extracted. Products, degradation products of the medium, and a small amount of antibiotics, etc. Mycelial residues contain residual culture medium, antibiotics and biologically active mycelia, which are potentially harmful to the ecological environment and have been regarded by the international community as one of the major public hazards of antibiotic production. At present, there are three main treatment methods for mycelium waste: one is to directly bury or dilute the mycelium and discharge it; the other is to dry and incinerate the mycelium waste; Add to fermentation raw materials for secondary use. Directly burying or diluting the mycelium and discharging i...
