Description

Technical Field

[0001] The present invention belongs to the technical field of soy product marinating, and particularly relates to a soy product marinating device and a marinating method. Background Art

[0002] Currently, marinated dried bean curd contains rich protein, fat, carbohydrates, and mineral elements such as calcium, phosphorus, and iron. These nutrients have various benefits for the human body, such as supplementing protein, reducing cholesterol, promoting heart health, preventing osteoporosis and anemia, etc. In addition, marinated dried bean curd also contains components such as lecithin and saponins, which help to scavenge free radicals in the body and inhibit the growth of tumor cells.

[0003] During the marinating process of marinated dried bean curd, in order to make it taste better, old brine is usually used for marinating. Old brine is formed after being used and seasoned multiple times, and has rich flavors and aromas, which can provide better taste and texture for marinated dried bean curd. During the marinating process, using old brine can make the dried bean curd more flavorful and the taste more delicious. At the same time, the spices and seasonings in the old brine will also penetrate into the dried bean curd, making its taste more intense. In addition, the salt and other seasonings in the old brine also help the dried bean curd to be better preserved and prevent spoilage.

[0004] There are marinating reaction kettles in the prior art, in which carriers are used to place soy products inside. Some have a top stretching structure. However, for the marinating of soy products in the carrier, it is easy to produce uneven marinating effects inside and outside, resulting in the situation that the outer soy products are completely marinated through, but the inside is not fully flavored yet.

The bean product braising equipment according to claim 1, characterized in that: The lifting tube (3) contains material bags and bean products, and a lifting ear (32) is provided on the top of the lifting tube (3), and the lifting ear (32) is connected to the transmission chain (23); a heating chamber is provided in the reactor (1), and a heating tube (13) is installed in the heating chamber; a temperature control plate (14) is installed on the outside of the reactor (1), and a temperature detector (15) is installed at the bottom of the reactor (1), the temperature control plate (14) is suitable for adjusting the temperature of the heating tube (13), and the temperature detector (15) is suitable for extending to the bottom of the reactor (1) to detect the temperature.

9. A soy product braising process using a braising device, characterized in that: The following steps are involved: The raw soybeans are soaked, ground, filtered, boiled, and marinated before being formed into tofu, dried tofu, and yuba to form bean products. Step 1, prepare a stewing material bag, place the stewing material bag in a hanging tube (3), and introduce no more than 20% of old brine; Step 2, connecting the top lifting lug of the lifting tube (3) to the bottom of the transmission chain (23), and the top is wound around the fixed sprocket (22), and the end is fixed to the traction wheel (69) of the lifting shaft (64); Step 3, placing the pre-placed bean products into the hanging barrel (3), and placing it downward in the installation cavity; the lifting motor (62) rotates to lift or lower the hanging barrel (3); a grid frame (16) is installed in the reaction kettle (1), and the grid frame (16) is suitable for supporting the hanging barrel (3); Step 4, fill with clean water and start braising; the braising time is 2-5.5 hours, and the heating temperature is 70-85°C; Step 5, then place the sampling box on the carrier plate (47), first push the outer tube (432) toward the reactor (1), so that the hinged rod (433) at the front end drives the closing plate (5) to open, so that the brine flows between the closing plate (5) and the sliding body (42), and then pull the edge outer plate (46) of the outer tube (432) on the side facing away from the reactor (1) to close the closing plate (5); then rotate the inner tube (431) relative to the outer tube (432) until the two groups of flow holes (44) are connected, and place the sampling tube (7) on the carrier plate (47) in advance. The sampling tube (7) automatically receives the brine in the inner tube (431). After sampling, push the push-pull rod (45) in the opposite direction to complete the separation of the two groups of flow holes (44) to achieve sampling; Step 6: After heating, cool and let stand for 12-24 hours to complete the marinating.
