Description

Technical Field

[0001] The present disclosure relates to the technical field of brewing equipment, and in particular to a saccharification tank. Background Art

[0002] Saccharification is an essential step in rice wine production and fermentation. Since the substrate for microbial fermentation is sugar, the starch in the rice must be converted into glucose for subsequent fermentation. Saccharification breaks down starch into easily digestible sugars like glucose and maltose. These sugars are then rapidly utilized by the microorganisms during fermentation, further enhancing the alcohol content, taste, and aroma of the rice wine.

[0022] Explanation of the accompanying drawings: 1-tank body, 101-tank body inner wall, 102-tank body outer wall, 2-bracket, 201-support leg, 3-ventilation structure, 31-first ventilation column, 32-second ventilation column, 4-water inlet pipe, 5-first valve component, 6-water outlet pipe, 7-second valve component, 8-flushing pipe, 9-third valve component, 10-water heater, 11-fourth valve component. DETAILED DESCRIPTION

[0023] like Figures 1 to 3 As shown, a saccharification tank disclosed herein includes a tank body 1, a bracket 2 and a ventilation structure 3, wherein the bracket 2 is arranged at the bottom of the tank body 1 and is connected to the tank body 1; the ventilation structure 3 includes a first ventilation column 31 and a second ventilation column 32, and the first ventilation column 31 and the second ventilation column 32 are both hollow cylinders. The first ventilation column 31 is arranged in the tank body 1 and is connected to the tank body 1, and the axial direction of the first ventilation column 31 is parallel to the axial direction of the tank body 1; the second ventilation column 32 is rotatably arranged in the tank body 1, and the axial direction of the second ventilation column 32 is perpendicular to the axial direction of the tank body 1.

[0024] Since the cooked rice to be saccharified placed at the bottom of the tank body 1 is not completely saccharified in the prior art, a ventilation structure 3 is provided in the tank body 1. The ventilation structure 3 includes a first ventilation column 31 and a second ventilation column 32. The first ventilation column 31 and the second ventilation column 32 are both hollow cylinders. The first ventilation column 31 is provided in the tank body 1 and connected to the tank body 1. The axial direction of the first ventilation column 31 is parallel to the axial direction of the tank body 1. The second ventilation column 32 is rotatably provided in the tank body 1. The axial direction of the second ventilation column 32 is parallel to the axial direction of the tank body 1. 1 is perpendicular to the axis of the trough body 1; illustratively, there is one first ventilation column, which is disposed in the middle of the trough body 1 and is connected to the trough body 1. Since the first ventilation column is a hollow cylinder and the rice grains to be saccharified are sticky, when the saccharified rice is poured into the trough body 1, the saccharified rice will wrap around the first ventilation column 31 without filling the hollow portion of the first ventilation column. The air in the hollow portion can come into contact with the saccharified rice, thereby improving the saccharification efficiency; and there are two second ventilation columns 32, which are disposed at both ends of the first ventilation column 31. The second ventilation columns 32 are controlled by connecting to a controller signal. The operator can control the start and stop of the second ventilation column 32 and the speed of the second ventilation column 32 through the controller. The controller can be implemented by a simple PLC (programmable logic controller).

[0025] Furthermore, in order to ensure a constant temperature during the saccharification process, the saccharification tank further includes a water inlet pipe 4, a water outlet pipe 6 and a flushing pipe 8;

[0026] The trough body 1 includes an inner wall 101 and an outer wall 102 of the trough body, and a closed gap is formed between the inner wall 101 and the outer wall 102 of the trough body; one end of the water inlet pipe 4 is connected to the closed gap, and the other end extends to the outside of the trough body 1, and is provided with a first valve component 5; one end of the water outlet pipe 6 is connected to the closed gap, and the other end extends to the outside of the trough body 1, and is provided with a second valve component 7; one end of the flushing pipe 8 is connected to the end of the water inlet pipe 4 extending outside the trough body 1, and the other end is arranged above the notch of the trough body 1, and is provided with a water outlet facing the trough body 1, and a third valve component 9 is provided near the water outlet.

[0027] Exemplarily, the inner wall 101 of the tank body can be a U-shaped groove, or a groove of other shapes, such as a flat-bottomed groove. Preferably, in one embodiment of the present disclosure, the inner wall 101 of the tank body is a U-shaped groove. Since the saccharification process must ensure that the temperature is stable at 30-40°C, the tank body 1 is designed to include the inner wall 101 of the tank body and the outer wall 102 of the tank body, and a closed gap is formed between the inner wall 101 of the tank body and the outer wall 102 of the tank body for heat exchange.

[0028] Specifically, an inlet pipe 4 and an outlet pipe 6 are provided, one end of the inlet pipe 4 is connected to the enclosed gap, and the other end extends outside the tank body 1 to be connected to the water source, and a first valve component 5 is provided; one end of the outlet pipe 6 is connected to the enclosed gap, and the other end extends outside the tank body 1 to be connected to the wastewater tank, and a second valve component 7 is provided; one end of the flushing pipe 8 is connected to one end of the water inlet pipe 4 extending outside the tank body 1, and the other end is provided above the notch of the tank body 1, and a water outlet facing the tank body 1 is opened, and a third valve component 9 is provided near the water outlet.

[0029] The first valve member 5, the second valve member 7 and the third valve member 9 can all use one-way valves to prevent backflow from affecting the inflow and outflow of liquid; the water inlet pipe 4 and the flushing pipe 8 can be connected to the same water source. After saccharification is completed, the first valve member 5 can be closed and the third valve member 9 can be opened to allow water to enter the tank body 1 for flushing. There is no need for the staff to hold a water gun for flushing, which facilitates the staff to carry out the next step of operation.

[0030] Furthermore, since the saccharification process needs to ensure that the temperature is stable at 30-40°C, it is necessary to ensure that the water temperature in the closed gap is suitable for heat exchange with the cooked rice to be saccharified in the tank body 1 to ensure that the cooked rice to be saccharified in the tank body 1 is maintained within a temperature range suitable for saccharification. Therefore, the saccharification tank also includes a temperature detection device (not shown in the figure) and a water heater 10. The temperature detection device is arranged on the inner wall 101 of the tank body; the water heater 10 is arranged at a place on the water inlet pipe 4 close to the closed gap, and is signal-connected to the temperature detection device.

[0031] Furthermore, after saccharification is completed, the cooked rice to be saccharified needs to be transferred to a fermentation tank for fermentation. Usually, the cooked rice to be saccharified needs to be transported to the fermentation tank manually, and this process will also affect the quality of fermentation. In order to reduce the impact and to facilitate the saccharified cooked rice to enter the next step of processing, a through hole is opened at one end of the tank body 1, and the inner wall 101 of the tank body is inclined toward the through hole. More specifically, the through hole is connected to the fermentation tank, so that the saccharified rice can directly enter the fermentation tank from the through hole.

[0032] Furthermore, if the inclination angle is too large, the cooked rice will be concentrated on the side of the tank body 1 close to the through hole, affecting the saccharification effect. Therefore, the inclination angle of the tank body inner wall 101 is 5 to 9 degrees.

[0033] Furthermore, due to the inclined design of the tank body 1, the rice to be saccharified tends to the end where the through hole is provided. In order to ensure that the rice to be saccharified does not directly enter the fermentation tank during saccharification, the saccharification tank also includes a fourth valve component 11, which is provided at the through hole and connected to the through hole.

[0034] Furthermore, the bracket 2 includes four supporting legs 201 , which are respectively arranged at four corners of the outer wall 102 of the tank body, and the four supporting legs 201 are all connected to the outer wall 102 of the tank body.

[0035] Furthermore, the hollow cylinder is a grid-shaped hollow cylinder.
