Technical Field

[0001] The utility model relates to the field of engineering control, in particular to a material temperature control device. Background Art

[0002] Some of the bubbly-flavored coagulated fermented yogurts on the market use slow fermentation of bacteria, and the process flow design adopts an online heating mode, heating the bacteria and materials together to the temperature required for bacteria fermentation. Since the bacteria have extremely demanding fermentation temperature adaptation, the temperature difference must be ensured to be within ±1°C to meet the fermentation process conditions. Otherwise, the product will fail to ferment.

[0003] At present, most manufacturers use electric heating and tubular heat exchangers to control the temperature of bacterial fermentation. The electric heating constant temperature method has the problems of high line modification costs and long equipment procurement cycles; while the tubular heat exchanger has the problems of large space occupied by the heat exchange equipment, great difficulty in maintenance and quality risks when leakage occurs in the tube, and difficult visual control; and the temperature fluctuations of these two types of equipment when they are kept constant are greater than 1°C, so they cannot meet the slow fermentation of the bacteria of the coagulated fermented yogurt, and the products produced cannot achieve the bubbly taste effect.

[0004] Chinese invention patent: "CN104432438A" discloses a constant temperature fermentation device, including a water bath, a heating box, a fermentation box, a drainage pump and an exhaust pump; the water bath is provided with a water inlet, a drainage outlet and an exhaust outlet, the water inlet is connected to the heating box through a water inlet pipe, a heating pipe is provided inside the heating box, the drainage outlet is connected to the drainage pump through a water outlet pipe, and the exhaust outlet is connected to the exhaust pump; the fermentation box is installed inside the water bath, a fixed guide column is provided at the bottom of the water bath, the fermentation box has a through hole passing through and is installed on the guide column through the through hole, a bracket is provided on the top of the fermentation box, the bracket includes a fixed column and a mounting plate, the bottom end of the fixed column is fixedly connected to the fermentation box, a mounting plate is installed on the top of the fixed column, a calibration hole is provided on the mounting plate, the calibration hole is located directly below the exhaust hole, the top of the guide column passes through the calibration hole, a piston is provided at the top of the guide column, and the size of the piston matches the exhaust hole. This invention patent achieves the effect of maintaining a constant temperature by setting a fermentation box in a water bath, but the temperature difference of the fermentation box cannot be controlled within ±1°C, so the constant temperature effect cannot meet the conditions for slow fermentation of the bubble-flavored coagulated fermented yogurt bacteria.

The downstream of the water pump 33 passes through the plate heat exchanger 4, in which the circulating water and the material exchange heat. The pipeline passes through the plate heat exchanger 4 and is connected to the mixer 2. The circulating water is mixed with steam in the mixer 2 for heating, flows to the water inlet 32 ​​and then enters the circulating water tank 3. A first temperature sensor 34 is also provided between the mixer 2 and the water inlet 32. The material tank 6 is used to store the material.
