Technical Field

[0001] The utility model relates to the technical field of quantitative ventilation for tea fermentation, in particular to quantitative ventilation equipment for tea fermentation. Background Art

[0002] Fermentation is a key step in the tea manufacturing process. Uneven fermentation due to insufficient moisture in the tea will reduce the quality of the tea and affect its sales.

[0003] A Chinese patent with publication number CN217218038U discloses a quantitative ventilation device for tea fermentation, including a fermentation barrel body, an outer wall of which is inlaid with a ventilation pipe, and the head end of the ventilation pipe is an air outlet, and the tail end of the ventilation pipe is an air inlet, a fixed pipe is fixed to the head end air outlet of the ventilation pipe, a small fan and a dustproof mechanism are arranged on the inner wall of the fixed pipe, the dustproof mechanism is arranged on the outside of the small fan, and the dustproof mechanism is movably installed between the small fan, the small fan is installed with the fixed pipe through a detachable mechanism, the detachable mechanism includes a card slot and a slot, the inner wall of the fixed pipe is symmetrically provided with the slot, and the outer side of the fixed pipe is symmetrically provided with a card slot communicating with the slot.

[0004] The above-mentioned prior art solutions have the following defects: the ventilation pipe in the above-mentioned technical solution is only embedded on the outer wall of the fermentation barrel body, and only one air outlet is provided, which means that the ventilation enters the interior of the fermentation barrel from a fixed point. This may lead to uneven ventilation, where the tea area close to the ventilation outlet is over-ventilated, while the area far from the ventilation outlet is insufficiently ventilated, and since ventilation is only carried out through one air outlet, the air circulation direction is limited, and multi-directional or omnidirectional ventilation cannot be achieved. This limits the uniform distribution of air inside the fermentation barrel and affects the uniformity of tea fermentation.

[0005] Therefore, we proposed a quantitative ventilation device for tea fermentation to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a quantitative ventilation device for tea fermentation, so as to solve the problems of the position and quantity of ventilation openings and the lack of multi-directional ventilation proposed in the above-mentioned background technology.

When ventilation needs to be stopped, the cylinder drives the block to completely cover the air inlet to achieve complete sealing; when ventilation is needed, the block is moved away to ensure smooth air entry.

[0015] Preferably, ventilation holes are provided above the support blocks on both sides of the inner wall of the fermentation cabinet, and the ventilation holes increase the air circulation inside the fermentation cabinet, which is conducive to the uniform fermentation of tea leaves and the control of humidity.
