The purpose of this utility model is to provide a multi-functional fermenter for probiotics in view of the above defects, which has the characteristics of uniform heating, rapid heating and energy saving.

The technical scheme of the utility model is: a multifunctional probiotic fermenter, including a tank body, an electric heating tube is arranged in the inner cavity of the tank, a heat conducting partition is arranged in the tank body, and the edge of the heat conducting partition and the The inner wall of the tank is sealed and matched to separate the inner cavity of the tank into two independent spaces, the fermentation chamber and the heat transfer medium chamber, and the electric heating tube is installed in the heat transfer medium chamber.

The heat conduction medium cavity is filled with heat conduction oil.

The heat-conducting medium chamber is also communicated with a heat-conducting medium expansion tank, and the heat-conducting medium expansion tank is fixed on the outer wall of the tank through a connecting pipe.

The fermenter also includes a stirring device, the stirring device includes a stirring blade arranged above the heat conducting partition, a transmission shaft is connected to the stirring blade, and the transmission shaft extends vertically downward through the heat conducting partition and the side of the tank body The wall is coaxially connected with the output shaft of the drive motor fixed on the outer wall of the bottom of the tank body.

A cooling coil is also provided in the fermentation chamber.

The tank body is an upright hollow cylinder structure, the heat-conducting partition is radially fixed on the inner wall of the tank, the outer edge of the heat-conducting partition matches and seals the inner wall of the tank, and the fermentation chamber is located at the upper part of the tank body. The heat conduction medium chamber is located at the lower part of the tank body.

The utility model adopts the above-mentioned technical scheme, which improves the existing direct heating method to the indirect heating method through the heat conduction medium, so that the temperature control of the tank body is more accurate, and it relatively increases the heat transfer area, making the tank The temperature of the tank rises more rapidly, reducing energy consumption. At the same time, due to the use of indirect heating, the heat transfer of the material in the tank is more stable, and there will be no burnt phenomenon during the fermentation process of the material, and the product quality is correspondingly improved.

Detailed ways

As shown in Figure 1, multifunctional probiotic fermentation tank of the present utility model comprises the tank body 1 of upright cylinder structure, and this tank body 1 adopts the stainless steel of double-layer jacket structure to make, to be beneficial to heat preservation; The bottom is provided with a bracket 11, and the top of the tank body 1 is provided with a tempered glass cover 3 for easy observation. A thermally conductive partition 2 is arranged radially at the lower part of the inner cavity of the tank body 1. The outer edge of the thermally conductive partition plate 2 fits and seals with the inner wall of the tank body 1, and separates the inner cavity of the tank body into the upper fermentation chamber 1-1 and the lower part. The heat-conducting medium chamber 1-2, the side wall of the tank body in the fermentation chamber 1-1 is provided with a feed inlet 4, a feed outlet 5, and a cooling water inlet and outlet, and the cooling water inlet and outlet are connected to a cooling coil 9 The cooling coil 9 is fixed on the side wall of the tank in the fermentation chamber 1-1, and the cooling coil 9 has a larger conduction area, which can accelerate the cooling of materials during fermentation. Add heat-conducting oil in the heat-conducting medium chamber 1-2 of the lower part, and the expansion tank 10 that is connected with this heat-conducting medium chamber is connected with this heat-conducting medium chamber through connecting pipeline on the outer wall of tank body, can supplement heat-conducting oil through this expansion tank 10 and Observe the liquid level of the heat transfer oil at any time. An electric heating tube 6 is arranged on the side wall of the tank body in the heat-conducting medium chamber 1-2, and a temperature sensor 7 is arranged on the heat-conducting partition. On instrument 8. The temperature controller 8 is also connected and controlled with a stirring device, which includes a stirring blade 13 arranged in the tank fermentation chamber 1-1 close to the heat conduction partition 2, and the transmission shaft of the stirring blade 13 extends vertically downward through the The output shaft of the drive motor 12 fixed on the outer wall of the bottom of the tank is connected through the transmission of the heat conduction partition 2 and the bottom of the tank body, wherein a waterproof sealed bearing 14 for sealing the transmission shaft is provided on the heat conduction partition 2 to prevent heat conduction Oil leakage contaminates the material in the fermentation chamber.
