The invention relates to an electric cooker. In order to improve the production efficiency by a simple structure even when the starch content of an object to be cooked is reduced during cooking, the present invention provides an electric cooker comprising: an inner container in which an accommodation space is formed; a separation plate which is attached to and detached from the interior of the inner container so as to divide the accommodation space into an upper side cooking area for accommodating an object to be cooked and a lower side water storage area for storing heated water, and has a siphon tube immersed in the heated water in the water storage area on the lower surface part so as to form an opening part in a way of connecting the siphon tube and the cooking area; a perforated platewhich is disposed at a distance from the opening part to the upper side and on which the object to be cooked is placed; and a separation plate gasket. When the inner container is heated, steam pressure of the water storage area is increased so as to arrange the heated water on the edge of the separation plate in a way of rising along the siphon tube to seal the space between the separation plateand the inner container.

The invention belongs to the technical field of steam-water separators, and particularly relates to a steam-water separator with a pressure recovery stage. The steam-water separator aims to reduce steam pressure loss at an outlet of a steam generator and improve the working performance of the steam generator. The steam-water separator is characterized by comprising an outlet cylinder, a secondaryhydrophobic passage, a secondary racemization plate, a secondary hydrophobic restricting ring, a secondary separation cylinder, a secondary positive rotary vane, a primary hydrophobic passage, a primary hydrophobic passage, a primary positive rotary vane, a guide vane, a primary hydrophobic restricting ring, a primary separation cylinder, a reverse vane center column, a reverse vane, a secondary positive vane center column and a primary positive vane center column. Therefore, the steam-water separator has the advantage of reducing the steam pressure loss at the outlet of the steam generator.

A full-automatic wort oxygenated yeast adding machine and a wort oxygenated yeast adding method relate to the technical fields of multi-material mixing processes of biological engineering, fermentation engineering, biological pharmacy, fine chemical engineering and chemical engineering. The full-automatic wort oxygenated yeast adding machine comprises a stand, a PLC (Programmable Logic Controller) control cabinet and a Venturi tube, wherein the PLC control cabinet is arranged on the outer side of the upper end of the stand; the Venturi tube is arranged above the stand; and the full-automatic wort oxygenated yeast adding machine is externally connected with an air compressor, a cold wort inlet, a fermentation tank, a yeast propagating tank and a steam pressure reducing station. The wort oxygenated yeast adding method comprises the following steps of: introducing cold wort through the cold wort inlet; introducing air into the air compressor; introducing yeast into the yeast propagating tank; mixing the cold wort, the air and the yeast in the Venturi tube; after mixing enabling the mixture to enter the fermentation tank. The wort oxygenated yeast adding method disclosed by the invention is feasible; due to the application of an air quality flowmeter and a volumetric flowmeter, reliable preconditions for accurate addition of oxygen and yeast to the wort are provided; the establishment of a mathematical model method provides reliable reference for the accurate addition of the oxygen and the yeast to the wort; due to the application of an open-loop control principle, the phenomenon of feedback regulation lagging in a closed-loop control is avoided; and the automatic control over the whole process is realized, so that the labor intensity and the human error probability are greatly reduced and further the quality and the uniformity of products are greatly improved.

The invention discloses a safe steam pressure sterilizer. The sterilizer comprises a metal block, wherein a heating device is arranged in the metal block; a helical passage is formed in the metal block; a mounting groove is formed in the center of the metal block, and a fixed block is arranged in the mounting groove; a channel is formed in the fixed block, and two ends of the channel are connected with the helical passage; the diameter in the middle of the channel is larger than the diameters of two sides of the channel; an annular groove is formed in the end part of the channel on the water incoming side; a first through hole communicated with the middle of the channel is formed in the annular groove; a slide bar matched with the channel is arranged in the channel on the water incoming side; one end, positioned in the middle of the channel, of the slide rod is vertically connected with a plate body which is provided with a second through hole; a sodium carbonate solution bottle is arranged at the water inlet end of the metal block, and is provided with a sprayer and a sprayer trigger; the sprayer trigger is connected with the slide rod through a stay wire; and a sodium carbonate solution is sprayed into the helical passage by the sprayer after the trigger is pulled by the slide rod. The steam pressure sterilizer can be used for automatically cleaning water scale on a steam pipeline after the water scale is formed in the pipeline.

The invention relates to a coal-fired unit variable rate load control method based on AGC instruction state change judgment, which comprises the following steps: an instruction receiving device receives a load instruction, generates an AGC instruction, acquires a main steam pressure signal and a generator power signal, and sends the signals to an industrial control computer; and the industrial control computer judges and processes the state of the AGC instruction, adopts different load variable rate strategies on a steam turbine side and a boiler side according to a judgment result, and then performs control operation on unit load and pressure according to a variable rate processing result to generate a control valve opening instruction of the steam turbine. The method has the beneficial effects that the AGC instruction is divided into a stable state and a dynamic state; in a stable state, the characteristic of rapid load adjustment of the steam turbine is exerted, and variable load adjustment is carried out at a high rate; under the dynamic working condition, load response is carried out at a conventional rate, the load regulation performance index of the unit is effectively improved, and the AGC response capability of the unit is improved.
