Description

Technical Field

[0001] The invention relates to the technical field of tea extract production, and more specifically to a tea soup concentrate production device. Background Art

[0002] The development and utilization of tea has a long history in my country. It is deeply loved by people and they regard tea drinking as a lifestyle. After modern scientific separation and identification, tea contains more than 450 organic chemical components and more than 40 inorganic mineral elements. Tea has at least the following effects: less sleep, calming the nerves, improving eyesight, clearing the head, quenching thirst, clearing heat, relieving summer heat, detoxifying, digesting food, sobering up, reducing weight, lowering qi, promoting diuresis, and relieving constipation. Therefore, tea is widely used in food and beverage, cosmetics, medical and health products and other fields.

[0003] Tea leaves are mainly used as tea concentrate extracted after steaming. The traditional production process of tea concentrate is as follows: add hot water and tea leaves to a heating tank, keep the temperature at a certain level and soak for a period of time, then drain the tea, and then add it to a concentration tank for concentration to obtain tea concentrate. The existing tea barrel soaking method usually removes the tea residue after soaking the tea leaves only once, resulting in some organic components and inorganic minerals still existing in the tea residue, resulting in a low extraction rate. In order to increase the extraction rate of substances in the tea soup, some people soak the tea leaves multiple times, but the efficiency is relatively low. To this end, we provide a tea concentrate production equipment. Summary of the invention

[0033] The soaking tank placement station shown in the above embodiment is three. In other embodiments, the soaking tank placement station can also be four or more.

[0034] The production process of the tea soup concentrate raw tea equipment of the present invention is as follows: 1. First, fix the filter bag on the filter bag support frame and tie it tightly, put tea leaves in it, and place it on the filter bag loading station; 2. The cover cylinder is pulled down to open the cover of the constant temperature immersion tank, and the power device drives the mobile trolley to move, driving the three filter bag support frame lifting devices to move to the right until the first filter bag support frame lifting device is aligned with the filter bag loading station; then the filter bag support frame lifting device is actuated to drive the lifting bracket to move downward, and lift the filter bag support frame upward to a position higher than the tank mouth of the constant temperature immersion tank; the power device drives the mobile trolley to move again, driving the three filter bag support frame lifting devices to move to the left until the first filter bag support frame lifting device is aligned with the tank mouth of the first constant temperature immersion tank, and then the filter bag support frame lifting device drives the lifting bracket to drive the filter bag support frame to move downward, so that the filter bag support frame is placed in the constant temperature immersion tank.

[0035] 3. Add soaking liquid (usually hot water) to the liquid inlet of the third constant temperature soaking tank, and then pump it into the first constant temperature soaking tank in turn by the liquid pump to soak the tea. After the first soaking time is completed, the tea soup in the first constant temperature soaking tank that has only been soaked for the first time is discharged.

[0036] 4. Repeat steps 1-3. The tea discharged from the first constant temperature soaking tank for the second time and thereafter is the tea that has been soaked three times.

[0037] 5. Then the tea soup in step 4 is transported to the hot liquid inlet of the heat exchange device to perform heat exchange (cooling) on ​​the tea soup; 6. The tea soup after heat exchange is discharged from the cold liquid outlet of the heat exchange device and enters into the filtering and concentrating device for filtration to obtain tea soup concentrate. The filtrate is discharged from the filtrate outlet and enters into the heat exchange chamber of the heat exchange device for heat exchange heating. After heating, it is added into the third constant temperature soaking tank as soaking liquid.
