Steam box and control method thereof

Abstract

The invention discloses a steam box and a control method thereof. The control method comprises the following steps: S1, acquiring data of at least two parameters of pressure, temperature and flow of apressure relief unit in a cavity of the steam box; s2, analyzing according to the obtained data to obtain a multi-feature parameter fusion result; and S3, adjusting the pressure in the steam box cavity according to the multi-feature parameter fusion result. In the step S2, a multi-feature parameter fusion result obtained according to the obtained data analysis comprises the steps of judging confidence intervals of all parameters by adopting an uncertainty analysis method, and outputting the multi-feature parameter fusion result. The pressure in the steam box cavity is adjusted according to the multi-feature parameter fusion result, so that active adjustment of the pressure in the steam box cavity is achieved, namely, the pressure in the steam box cavity is accurately adjusted and controlled, the cooking process can be accelerated by controlling the pressure in the steam box cavity, and the cooking time is shortened.

Description

technical field [0001] The invention belongs to the technical field of cooking equipment, and in particular relates to a steamer and a control method thereof. Background technique [0002] The steam box is a kitchen appliance that converts water into high-temperature steam to cook food with 100% steam. Precise temperature control, locking nutrition, reducing fat and salt, maintaining the original taste of food and full of umami. [0003] The pressure relief valve is one of the components on the steam box, which can release the pressure and exhaust the steam box. The existing pressure control steamer and pressure steamer all add a purely mechanical pressure relief valve at the steam outlet of the steamer. When the internal pressure of the steamer cavity reaches the maximum pressure that the pressure relief valve can withstand, the pressure relief valve will The pressure valve opens to release the pressure in the cavity. The pressure relief valve is a kind of opening and cl...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the existing purely mechanical pressure relief valve can only realize the control of a fixed pressure value, and cannot accurately control the internal pressure of the steamer cavity for different food materials.
