Embodiment 1

[0039] A new process for desalination of soy sauce residue, the steps comprising:

[0040] 1) Crush the soy sauce residue into granules, and select the soy sauce residue particles with a particle size of 0.9-2.8 mm as the material to be processed.

[0041] 2) 6g of soy sauce residue particles are evenly distributed in the material tray 10, the bed height is 7.5mm, and a round hole with a diameter of 2mm is opened at the bottom of the material tray, so that superheated steam can pass through the material and fully contact with the material.

[0042] 3) Put the quartz tube fluidized bed 6 into the muffle furnace 5, and turn on the muffle furnace to raise the temperature.

[0043] 4) When the temperature in the fluidized bed rises to 130°C, open the superheated steam valve 3 of the steam generator 1, and pass the superheated steam into the fluidized bed dryer for preheating treatment.

[0044] 5) When the superheated steam temperature in the fluidized bed dryer reaches and stabi...

Abstract

The invention relates to a desalting process of soy sauce residue, which comprises the following steps: 1) pulverizing soy sauce residue; 2) uniformly distributing materials to be treated in material trays; 3) putting a fluidized bed dryer into a muffle furnace and Preheating; 4) When the temperature in the fluidized bed dryer is stable, superheated steam is introduced; 5) When the flow rate and temperature of the superheated steam are stable, put the material tray and the materials to be processed, and start drying; 6) Drying of soy sauce residue for 18 ‑60min, when the moisture content of the material drops below 12%, the drying is over; 7) Close the muffle furnace, let off the waste gas in the steam generator and then close the steam generator; 8) Take out the material tray and complete the desalination of soy sauce residue . The soy sauce dregs desalting process and system of the present invention, the salt content in the soy sauce dregs treated with superheated steam is reduced by about 30%, the nutritional components can be better preserved, and the final moisture content of the material is below the safe storage moisture, which can last for a long time Storage, and high processing efficiency, no pollutant discharge.

Description

technical field [0001] The invention belongs to the field of biological waste treatment, in particular to a soy sauce residue desalination process and system, and is especially suitable for the cleaning treatment and utilization of soy sauce residue. Background technique [0002] Soy sauce residue is a by-product of brewing soy sauce, which is rich in nutrients and is of great significance to the comprehensive utilization and development of soy sauce residue. During the brewing and fermentation process of soy sauce, a large amount of salt is usually added to inhibit bacteria and prevent spoilage. Therefore, soy sauce dregs contain a lot of salt, which is the main reason for affecting the secondary utilization of soy sauce dregs. In addition, the moisture content of soy sauce residue is relatively high. If it is not treated in time, it is prone to corruption and deterioration, which is not conducive to long-term storage. [0003] Yang Mingquan introduced a method of reducing...
