A mixer for extracting shellfish toxins

Abstract

The invention relates to shellfish extraction equipment, in particular to a mixer for extracting shellfish toxins. The stirrer for extracting shellfish toxins includes a stirring tank, the tank wall of the stirring tank is provided with a heating and heat preservation device, the heating and heat preservation device includes an insulation layer and a constant temperature jacket layer, and the stirring device includes a motor on the top of the stirring tank, connected with the motor and located on the The drive shaft at the axis of the stirring tank and the stirring impeller located on the drive shaft, the drive shaft includes an upper half shaft and a lower half shaft arranged at intervals, several rigid springs are arranged between the upper half shaft and the lower half shaft, and the stirring impeller includes an upper half shaft and a lower half shaft The turning impeller and the down-pressing impeller, the up-turning impeller is sleeved on the upper half shaft, the down-pressing impeller is set on the lower half-shaft, and the free end of the fan blade of the up-turning impeller is obliquely upward. The invention has the beneficial effects of ensuring constant internal temperature, improving stirring efficiency, shortening the time required for stirring, and facilitating discharging after the stirring is completed.

Description

technical field [0001] The invention relates to shellfish extraction equipment, in particular to a mixer for extracting shellfish toxins. Background technique [0002] At present, the most important step in the production process of extracting shellfish toxins is to put white and clean shellfish into the reactor, add appropriate amount of water, add suitable reactants, adjust the pH within the design range, and control the temperature at 45 ~55°C, stirring for 3~10 hours; during this process, the temperature inside the reaction device should be controlled at 45~55°C. The control of this temperature is more critical, but the reactor in the prior art directly drives the internal stirring device to stir through the stirring motor, so the temperature is not constant and uneven. The phenomenon of exchange causes the temperature in the reactor to not be kept constant. Moreover, the fan blades used in the stirring device in the reactor in the prior art have the same stirring dire...

AI Technical Summary

Problems solved by technology

The control of this temperature is more critical, but the reactor in the prior art directly drives the internal stirring device to stir through the stirring motor, so the temperature is not constant and uneven. The phenomenon of exchange, resulting in the temperature in the reactor can not be kept constant

Moreover, the fan blades used in the stirring device in the reactor in the prior art have the same stirring direction for the reactants. Although the reactants can be stirred around the axis direction, the vertical direction cannot obtain a larger range. The overturning reduces the stirring efficiency and prolongs the required stirring time. After the stirring is completed, the material can only be discharged from the discharge hole by the gravity of the reactant. When the material is discharged while stirring, it is easy to form a disturbance at the discharge hole. Flow, not easy to discharge
