Disclosed are a hydraulic combined steam leaching type integrated edible oil press and a method for processing edible oil with the press. The invention belongs to the field of edible oil processing. The invention solves the problems of low oil yield, residual harmful substances and poor economic efficiency in the existing pressing production process. The invention includes the comprehensive utilization of two functions of hydraulic pressure and leaching. Method: 1. Crush the oil plant, and then put it into the press from the feed port; 2. Send steam into the oil plant through the water vapor hole on the oil-water-vapor separation partition plate, and the oil outlet at the lower part of the press chamber will start to drip. Stop sending steam and keep warm at 85-100°C; 3. Start the press, set the pressure and propulsion speed of the hydraulic cylinder, and press oil at a constant temperature of 85-100°C until the oil is discharged from the lower part of the press chamber. 4. Unload the pressed oil cake, and then reinstall the oil-water-vapor separation partition into the press. Pushing the push plate through the hydraulic cylinder to extract oil, combined with high-temperature steam leaching, the oil yield can reach more than 18%.

The invention belongs to the technical field of production and processing of cold pressing edible oil, and particularly relates to a production method of cold pressing peanut and wheat germ compound oil. The production method of the cold pressing peanut and wheat germ compound oil comprises the following steps: (1) preprocessing of wheat bran, (2) preprocessing of peanut kernels, (3) modifying, (4) cold pressing and (5) filtering, wherein the specific steps of (3) modifying are as follows: uniformly mixing the preprocessed wheat bran and the peanut kernels with the weight ratio of (1-2):(4-12) to prepare a raw material, adding water, with the weight of 2%-4% of the weight of the raw material and the water temperature of 60-80 DEG C, to the raw material, and keeping 40-60 minutes for waterabsorption and softening. In the method, the wheat bran added to the peanut kernels can increase the oil yield of the peanut kernels; in addition, the peanut and wheat germ compound oil prepared by the method is rich in vitamin E, and integrates the nutritional functions of peanut oil and wheat germ oil, and the nutritional value is increased.

The invention discloses an air-conditioning system and a control method thereof. The air-conditioning system comprises: a compressor, including a casing, a first liquid accumulator, a second liquid accumulator, a first cylinder and a second cylinder; the first A cylinder and a second cylinder are arranged in the casing; the first cylinder is connected to the air outlet of the first liquid reservoir through a first suction pipe, and the second cylinder is connected through a second suction pipe the air outlet of the second accumulator; the compressor discharges the refrigerant compressed by the first cylinder and the refrigerant compressed by the second cylinder through a first exhaust port and a second exhaust port respectively an oil separator, the oil separator is provided with a first air inlet, a third air outlet and a first oil outlet; the first air inlet is connected to the second air outlet. The present invention can improve the energy efficiency of the air-conditioning system and at the same time reduce the oil output rate of the compressor, so that the air-conditioning system can run stably.
