RU198403U1 - Household tea fermenter with cooling function - Google Patents

Abstract

The utility model relates to the tea industry, as well as to the food industry, and can be used for fermenting tea in everyday life. The technical result of the utility model is to reduce energy consumption for heating and maintaining the temperature in the fermented mass, as well as expanding the functionality and increasing the safety of raw materials after fermentation by cooling. The device for fermentation of tea (Fig. 1) contains a housing of a household fermenter 4 with one compartment, inside of which the fermentable mass 1 is placed on a stand 6 in a container 2. At the bottom of the device there is a heating-cooler (peltier element) 10 so, that its upper part is located inside the device (gives off heat when the fermented mass is heated), and the lower part is outside (it is cooled, taking away the heat from the environment). For efficient heat transfer, radiators 8 and 9 are attached to the peltier element on both sides, and fans can be installed on them to intensify heat transfer. For better air convection, there is a fan 7 inside the device. The temperature inside the device is maintained using a temperature sensor 3 and a control device 5.

Description

The utility model relates to the field of the tea industry, as well as to the food industry, and can be used for fermentation of tea in everyday life.

A device for the fermentation of tea is known, consisting of a housing and air-conditioning air injection systems equipped with mixing and unloading drums installed respectively in the central and lower parts of the housing, made in the form of a truncated pyramid with double walls, between which heaters are installed, while on the inner wall of the housing, opposite the mixing drums, holes are made with nozzles placed in them [1].

The closest adopted for the prototype is a device consisting of a camera, a resistive heating element, a fan, a temperature sensor and a control device [2].

The disadvantages of these devices are the use of inefficient resistive heating elements, as well as the lack of cooling after fermentation, in which the fermentable raw material could be inside for a long time and not sour, until it is transferred to the dryer.

A feature of the operation of household devices is the periodic presence of the operator, and the time of automatic operation during the period without the operator can reach 24 hours or more. Therefore, it is necessary that the device for fermenting tea not only automatically maintains the fermentation parameters, but also preserves the fermentable raw materials after fermentation up to 24 hours. The preservation of raw materials is possible by slowing down the biochemical processes occurring during fermentation, for example, when the fermented mass is cooled to 5 ° C, otherwise the raw material will become sour for a long time.

The claimed utility model is illustrated in FIG. 1.

The figure 1 shows a household fermenter for tea fermentation with the function of cooling tea, where 1 is the fermentable mass, 2 is the container for the fermentable mass, 3 is the temperature sensor, 4 is the housing of the fermenter, 5 is the control device, 6 is the stand for the tank with the fermentable mass, 7 - fan, 8 and 9 - radiators, 10 - heater-cooler (Peltier element).

The technical result of the utility model is to reduce energy consumption for heating and maintaining the temperature in the fermented mass, as well as expanding the functionality and increasing the safety of raw materials after fermentation by cooling.

A device for fermenting tea (Fig. 1) contains a housing of a household fermenter 4 with one compartment, inside of which a fermentable mass 1 is placed on a stand 6 in a container 2. At the bottom of the device there is a heater-cooler (Peltier element) 10 so that its upper part located inside the device (gives off heat when the fermented mass is heated), and the lower part is on the outside (it is cooled, taking the heat of the environment). For effective heat transfer, radiators 8 and 9 are attached to the Peltier element on both sides, and fans can be installed on them to enhance heat transfer. For better convection of air inside the device there is a fan 7. The temperature inside the device is maintained using a temperature sensor 3 and a control device 5. The fermentation time is 8-24 hours, a temperature of 30-40 ° C, these values can be set using the buttons on the control device. At the end of the fermentation process, the supply polarity of the heating element (Peltier element) is changed using the polarity change unit in the control device, after which the fermented mass is cooled to 5 ° C. Cooling the mass is necessary to preserve the raw material from souring, when the operator after the end of the fermentation is not possible to immediately transfer the sintering mass to the dryer.
