实施例一Example 1
在采用脉冲电场对生物原料进行油脂提取时，大多使用高压交流电源进行处理，不利于油脂的析出和后续残渣蛋白的利用；低压直流脉冲电源处理的操作难度小、节省能源，同时处理所产生的热量对油脂和蛋白造成的影响很小。基于存在的问题，本申请提出一种脉冲电流发生器用于提供低压直流电场处理生物原料，进行油脂提取，从而提高油脂提取的效率和成果。When pulsed electric field is used to extract oil from biological raw materials, high-voltage AC power is mostly used for processing, which is not conducive to the precipitation of oil and the subsequent utilization of residual protein; low-voltage DC pulsed power processing is less difficult to operate and saves energy. Heat has little effect on fat and protein. Based on the existing problems, the present application proposes a pulse current generator for providing a low-voltage DC electric field to process biological raw materials and extracting oil, thereby improving the efficiency and results of oil extraction.
图1为本申请实施例一提供的一种脉冲电流发生器的结构示意图，本实施例提供的脉冲电流发生器可适用于对生物原料浆液进行破胞、油脂提取等加工方法中。FIG. 1 is a schematic structural diagram of a pulse current generator provided in the first embodiment of the application. The pulse current generator provided in this embodiment can be used in processing methods such as cell disruption and oil extraction of biological raw material slurry.
如图1所示，本申请实施例提供一种脉冲电流发生器，包括：直流电源U、继电器K和控制器S；As shown in FIG. 1 , an embodiment of the present application provides a pulse current generator, including: a DC power supply U, a relay K, and a controller S;
所述控制器S与所述继电器K电连接；The controller S is electrically connected to the relay K;
所述继电器K串联在所述直流电源U对负载R供电的回路中，所述控制器S用于基于预设脉冲参数控制所述继电器K的闭合与断开，以产生脉冲电流驱动负载R。The relay K is connected in series in the circuit in which the DC power supply U supplies power to the load R, and the controller S is used to control the closing and opening of the relay K based on preset pulse parameters to generate a pulse current to drive the load R.
直流电源U对负载R供电形成回路，继电器K串联于回路中，继电器K在控制器S的控制下根据预设脉冲参数进行闭合和断开，产生脉冲电流；在一实施例中，在继电器K闭合时，负载R与直流电源U接通，回路中产生电流，在继电器K断开时，负载R与直流电源U的回路断开，回路中无电流，继电器K在预设的开关时间和预设频率下不断的闭合和断开，回路中产生预设波形的脉冲电流，脉冲电流驱动负载R。其中，预设脉冲参数包括脉冲电流产生的总时间和一个脉冲周期内的开关时间(占空比)等。在本实施例中，控制器S为可编程逻辑(Programmable Logic Controller，PLC)控制器，可以用来在内部存储程 序，执行逻辑运算和顺序控制、定时、计数和算术运算等操作的指令。通过PLC控制器调节继电器K的开和关的时间，以调整产生的脉冲电流的占空比。采用继电器导通和断开回路，响应时间短，对波形影响小，脉冲电流的波形好、不失真。The DC power supply U supplies power to the load R to form a loop, the relay K is connected in series in the loop, and the relay K is closed and disconnected according to preset pulse parameters under the control of the controller S to generate a pulse current; in one embodiment, in the relay K When closed, the load R is connected to the DC power supply U, and a current is generated in the circuit. When the relay K is disconnected, the load R is disconnected from the circuit of the DC power supply U, and there is no current in the circuit. Assuming that the frequency is continuously closed and opened, a pulse current with a preset waveform is generated in the loop, and the pulse current drives the load R. The preset pulse parameters include the total time for generating the pulse current and the switching time (duty cycle) in one pulse period, and the like. In this embodiment, the controller S is a programmable logic (Programmable Logic Controller, PLC) controller, which can be used to store programs in the interior to execute instructions for operations such as logical operations and sequence control, timing, counting, and arithmetic operations. The on and off time of the relay K is adjusted by the PLC controller to adjust the duty ratio of the generated pulse current. The relay is used to turn on and off the circuit, the response time is short, the influence on the waveform is small, and the waveform of the pulse current is good and not distorted.
示例性的，在实际提取油脂的操作中，生物原料浆液的处理效果，即油脂的提取效率，主要受到脉冲电场的电场强度影响。设置脉冲电流产生的总时间为10800s，设定继电器K的闭合和断开时间分别为1s，便可产生频率为0.5Hz，占空比为50％且响应时间在10ms以内的直流脉冲电。本申请实施例中的脉冲电流发生器可产生脉冲周期大于0.1s的脉冲电流。Exemplarily, in the actual oil extraction operation, the treatment effect of the biological raw material slurry, that is, the oil extraction efficiency, is mainly affected by the electric field strength of the pulsed electric field. Set the total time of pulse current generation to 10800s, and set the closing and opening times of relay K to be 1s, respectively, to generate DC pulses with a frequency of 0.5Hz, a duty cycle of 50% and a response time of less than 10ms.

In the pulse power supply in the related art, the high-voltage solid-state switching loss is large, the heat is serious, and the vacuum tube switching stability is poor, the consistency is poor, and the switching speed is slow. The equipment cooling problem brought about by the rectangular pulse achieves the effect of short switching response time, simple production and less heat generation while generating a rectangular pulse current with a preset width, a larger amplitude and a preset period, which improves the application The effects of processing methods such as cell disruption and oil extraction of biological materials can better achieve the technological purposes of cell disruption and oil droplet coalescence.
实施例二Embodiment 2
图2为本申请实施例二提供的一种脉冲电流发生器的结构示意图，如图2所示，本申请实施例提供一种脉冲电流发生器，在上述实施例的技术上，可选的，所述负载还包括反应容器C。FIG. 2 is a schematic structural diagram of a pulse current generator provided in Embodiment 2 of the present application. As shown in FIG. 2 , an embodiment of the present application provides a pulse current generator. In terms of the technology of the above embodiment, optionally, The load also includes reaction vessel C.
示例性的，脉冲电流发生器产生的脉冲电流作用于反应容器C，反应容器C中的生物原料浆液在脉冲电流的作用下得到处理液。其中，脉冲电流的作用包括两种，其一，在脉冲电流作用的过程中，细胞膜内外的带电粒子随电流方向移动，在细胞膜内外产生电势差，促进细胞破裂及油脂的析出；其二，在脉冲电流停止的过程中，可以促进反应容器C内温度降低，有效降低热效应带来的负面影响，且脉冲电流停止时，脂滴等带电粒子不再受电流作用，反而开始无规则布朗运动，当电路重新导通时带电粒子再次跟随电流移动，能够显著促进电流对细胞的破坏作用和脂滴的聚并作用。Exemplarily, the pulse current generated by the pulse current generator acts on the reaction vessel C, and the biological raw material slurry in the reaction vessel C obtains the treatment liquid under the action of the pulse current. Among them, the role of the pulse current includes two kinds. One is that during the action of the pulse current, the charged particles inside and outside the cell membrane move with the direction of the current, and a potential difference is generated inside and outside the cell membrane, which promotes cell rupture and the precipitation of oil; During the process of stopping the current, the temperature in the reaction vessel C can be reduced, and the negative influence caused by the thermal effect can be effectively reduced. When the pulse current stops, the charged particles such as lipid droplets are no longer affected by the current, but instead start irregular Brownian motion. When re-conducting, the charged particles move with the current again, which can significantly promote the current's destructive effect on cells and the coalescence of lipid droplets.
