A water level sensor (91) is provided in an auxiliary tank (39) whose bottom portion communicates to a bottom portion of a pot (41) for generating steam and which is opened to the atmosphere. When water in the pot (41) keeps boiling and the stop time of a pump (35) reaches a predetermined time (e.g., 60 sec.), the pump (35) is driven for a predetermined time (e.g., 6 sec.) to supply water to the pot (41). This temporarily suppresses the boiling of water in the pot (41), lowering a steam pressure in a space formed by an external circulation passage (60), a heating chamber, and the pot (41). The water level in the auxiliary tank (39) then returns to a normal one, making it possible to correctly detect the water level in the pot (41).

ActiveCN101818985ATake away quicklyReduce steam pressureDrying using combination processesDrying solid materials with heatSteam pressureNitrogen
The invention discloses a novel drying oven. The novel drying oven comprises an oven shell, an air exhaustion hole, an air inlet, a flat plate and a support used for placing the flat plate, wherein a tray used for placing dried materials is arranged on the flat plate; the flat plate is an air-permeable type flat plate; and an air inlet tube is arranged on a drying box for inlet nitrogen or carbon dioxide or inert gases. In the novel drying oven, steam evaporated from wet materials to be dried can be quickly exhausted through an air-permeable structure due to the adoption of the air-permeable type flat plate, and the mass transfer is rapid, so steam pressure of the evaporated steam is lowered, the steam is not easily detained and condensed, and the drying speed is greatly improved; and under the condition of introducing a proper gas such as nitrogen into the air inlet tube, permeable holes can obviously improve the flowing and distribution of the nitrogen in the drying oven, so the steam at all parts of the drying oven can be quickly taken away along with the nitrogen, and the drying speed is further quickened.

Low pressure, low velocity steam injector
A direct steam injector for use in cooking food products by injecting live steam directly into the product to heat the food to cook temperatures. The injector operates under relatively low source steam manifold pressure while urging the valve return spring wide open, thus reducing the pressure of the steam flowing into the product. In addition to reducing the pressure of the steam, the steam injector reduces the velocity of the steam and better distributes it as the steam exits the injector, thereby reducing damage to the food product.
