Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to an exhaust control component of a steam cabinet. Background Art

[0002] Steam cabinets are widely used in the field of pastry processing, and their main function is to steam pastries. The working principle of the steam cabinet is: hot steam is introduced to heat the pastries in the steam cabinet to make them mature. After steaming is completed, the hot steam is quickly discharged, and then the cabinet door is opened to transport food.

[0003] After checking the public (announcement) number: CN218186304U, an independent exhaust steam cabinet is disclosed, whose exhaust control component includes a control gate, an adjustment component and a gate fixing mechanism, the control gate is used to close the exhaust port under normal pressure; an exhaust pipe is arranged outside the exhaust port, the gate fixing mechanism includes a movable valve plate, the movable valve plate is hinged to the exhaust port, and when the control gate falls, the exhaust port is closed; a counterweight block is arranged on the control gate, and the counterweight can be used to facilitate the buckling of the control gate, and a slight force will not cause the control gate to open, and the pressurized state in the cabinet will not cause the control gate to open Air leakage; the adjusting assembly includes a lifting screw and a fixing assembly, the lifting screw drives the movable valve plate to lift up along the exhaust pipe, the fixing assembly includes a fixing ring, the fixing ring is arranged in the exhaust pipe, one end of the movable valve plate and one end of the control gate are connected to the fixing ring; the adjusting lifting screw comes with a locking nut, each time adjustment is made, the locking nut is loosened first, and then the adjusting screw is used to lift or lower the movable valve plate, the adjusting screw is tightened clockwise to lift the movable valve plate, and the screw is adjusted counterclockwise to lower the movable valve plate, the lifting screw is fixed to another nut, the nut is welded to the inner ring of the fixing ring, and the fixing ring is welded in the exhaust pipe.

[0004] In the structure of the above-mentioned independent exhaust steam cabinet, although the movable valve plate can be automatically pushed open when the pressure in the cabinet is too high, when the cabinet is exhausted, the screw rod needs to be manually adjusted to lift the movable valve plate. For steam cabinets that need to perform intermittent steaming on the opposite points (intermittent steaming means: after steaming for a period of time, exhaust is achieved, and then the exhaust port is closed and steaming is continued, and this cycle is repeated), the above-mentioned exhaust control component is obviously not convenient for exhaust, because each time exhaust is performed, the screw rod needs to be manually adjusted to lift the movable valve plate, and after the exhaust is completed, the screw rod needs to be manually adjusted to lower the movable valve plate to close the exhaust port.
