Technical Field

The invention relates to the technical field of vegetable oil squeezing, in particular to a vegetable oil squeezing production system.

Background

The edible vegetable oil is one of the most important daily foods of people, and is rich in unsaturated fatty acids such as oleic acid, linoleic acid and linolenic acid, and trace elements such as zinc, manganese, copper and boron which are necessary for human bodies. The vegetable oil not only can provide heat and nutrient components necessary for human bodies, but also is beneficial to the absorption of various fat-soluble vitamins by people, and ensures the health of the human bodies and the nutrient balance of metabolism.

The squeezing method is produced by adopting a pure physical squeezing oil-making process, does not involve adding chemical substances, reserves the original rich nutrition of plants, has no chemical solvent pollution, and does not contain any chemical anti-corrosion antioxidant. Ensures the safety, nutrition and delicacy of the product, meets the requirements of human health, and is suitable for long-term reassurance eating.

The process control of the vegetable oil plants is very important in the process of squeezing out oil, and the key point for ensuring that the screw oil pressing is smoothly carried out and the quality of crude oil is stable according to requirements is achieved. If a large amount of materials are fed in the squeezing process, the discharging is not smooth, and a squeezing chamber is possibly blocked by oil, so that a squeezer is blocked and blocked; or when the oil contains stones, metals and other impurities, the impurities enter the barrel to cause the blocking and the blocking of the squeezer. After the blocking and blocking of the squeezer, the squeezing motor continuously generates heat to damage the motor.

In order to avoid damage caused by locked rotor blocking in the oil pressing process, in the prior art, CN103419391A detects the load current of the oil press through a current sensor, and when the load current is lower than a threshold value, it is determined that the locked rotor blocking occurs in the oil press, and oil pressing is stopped. However, different oil materials have different densities and hardness and have different functions from the motor, so that the load currents are different, and the fact that the only load current is adopted cannot accurately judge whether the different oil materials are locked or not.

In order to more clearly illustrate the technical solutions of the present invention, the present invention will be briefly described below by using embodiments, and it is obvious that the following description is only one embodiment of the present invention, and for those skilled in the art, other technical solutions can be obtained according to the embodiments without inventive labor, and also fall within the disclosure of the present invention.

A vegetable oil press production system according to a first embodiment of the present invention, as shown in fig. 1, includes a press section, a heating section, a rotational speed sensor, a state determination section, a motor control section, and an alarm section.

And the pressing part is used for adding the vegetable oil raw material to press. The pressing part can press oil by a screw in a pressing chamber, and the screw in the pressing chamber can be a double screw or a single screw. And a heating section for heating the press section. The heating part may include a heating coil, and a heating temperature of the heating part may be controlled by controlling a current passing through the heating coil.

A motor control part which turns off the pressing motor when the state determination part determines that the oil press is in a locked state; and the alarm part gives alarm information after the motor control part closes the squeezing motor. The alarm part may include an audible and visual alarm device and/or an image alarm device, wherein the image alarm device may include a liquid crystal display screen.

The vegetable oil squeezing production method of the vegetable oil squeezing production system provided by the embodiment of the invention comprises the following steps: adding the vegetable oil raw material into a squeezing part for squeezing; monitoring the rotating speed of a squeezing motor; when the running rotating speed of the pressing motor is less than a threshold value, judging that the oil press is in a locked-rotor and locked state; and when the oil press is in a locked state, the pressing motor is turned off and an alarm signal is given.

Further, in order to control the temperature of the pressed oil in the prior art, CN103419391A adopts a method of detecting the temperature in the barrel through a temperature sensor, turning off a heating coil when the temperature in the barrel is greater than a high temperature threshold, and turning on the heating coil when the temperature in the barrel is lower than a low temperature threshold, so as to keep the temperature in the barrel between the high temperature threshold and the low temperature threshold. However, this method requires the detection of the barrel temperature by means of a temperature sensor, while its regulation is carried out after a temperature greater than a threshold value, the temperature inside the barrel varying constantly between a high temperature threshold value and a low temperature threshold value, instead of being maintained at the optimal pressing temperature.

The preferred embodiment of the present invention further provides a vegetable oil press production system, which can maintain the pressing temperature at the optimum pressing temperature, thereby ensuring the oil yield and the quality of pressed oil. Referring to fig. 2, the vegetable oil pressing production system according to the preferred embodiment of the present invention includes a pressing section, a heating section, a rotational speed sensor, a state determination section, a motor control section, an alarm section, a storage section, a calibration section, a current sensor, and a heating controller.

The storage part stores the optimal pressing temperature of different types of vegetable oil raw materials; wherein, the vegetable oil raw materials of different types comprise peanuts, corns, soybeans, sesames, castor beans, sunflower seeds, tea seeds, rapeseeds, walnuts, flaxseeds, peony seeds and the like. And the pressing part is used for adding the vegetable oil raw material to press.

And the calibration part calibrates the corresponding control relation between the current and the heating temperature of the pressing motor of the oil press for different vegetable oil raw materials. Factors affecting the temperature in the press barrel of the press section include: the heating temperature of heating portion, the heat that the interaction produced and the heat dispersion of oil press itself are squeezed to the pole. The heat dissipation performance of the oil press is constant, the interaction magnitude corresponds to the load current of the press motor when the oil material is pressed by the pressing rod, therefore, for the optimal pressing temperature, the load current is fixed, that is, the heating temperature for keeping the optimal pressing temperature corresponding to the load current can be determined. Therefore, for a specific type of vegetable oil raw material, a constant current is applied to a pressing motor of the oil press through a constant current power supply at a standard working temperature, the heating temperature is adjusted to stabilize the temperature in a barrel of the oil press at an optimal heating temperature, and then the heating temperature is a control heating temperature corresponding to the constant current.

And a current sensor for detecting the real-time current of the press motor of the press section. A heating control part which controls the heating part to heat the pressing part to the optimal pressing temperature before the pressing motor is started, so that the pressing part is at the optimal pressing temperature when the pressing is started; after the pressing motor is started, the heating temperature is adjusted in real time according to the real-time current of the pressing motor and the corresponding control relation between the current of the pressing motor and the heating temperature of the pressed raw material, so that the temperature of a barrel of the pressing part is kept at the optimal pressing temperature in the pressing process.
