Description

  The present invention relates to a pickle liquid injector that injects a pickle liquid into raw meat.

  In the processing process of processed meat products such as ham, when the pickle liquid is injected into the raw meat, what is called a pickle liquid injector is generally used. As described in Patent Document 1, in the pickle liquid injector, a large number of needles are attached to the injection head above the feed conveyor, and raw meat is fed by the feed conveyor. Further, a pickle liquid supply source is connected to the injection head, the pickle liquid is supplied to each needle, the injection head is lowered by the drive mechanism, each needle pierces the raw material meat, and the pickle liquid is injected into the raw material meat.

  In this case, the problem is the injection amount of the pickle liquid. It is preferable to keep the weight ratio constant by making the injection amount correspond to and proportional to the weight of the raw meat. Furthermore, it is required to change the weight ratio depending on the type of product. For example, some products require 20% of their weight to be pickle liquid, while other products require 30% of their weight to be pickle liquid. Until now, it was not easy to make the injection amount correspond to the weight of the raw meat.

  Therefore, the present invention has been made for the purpose of making the injection amount correspond to the weight of the raw meat when the pickle liquid is injected into the raw meat in the pickle liquid injector for injecting the pickle liquid into the raw meat.

It is a side view which shows the Example of this invention. It is a top view of the injector of FIG.

  Examples of the present invention will be described below.

  FIG. 1 shows a pickle liquid injector according to the present invention. In this injector, a number of needles 2 are attached to the injection head 3 above the feed conveyor 1, and the raw meat 4 is fed by the feed conveyor 1. The feed conveyor 1 comprises a belt conveyor or a roller conveyor.

  Further, the pickling liquid supply source is connected to the injection head 3, the pickling liquid is supplied to each needle 2, the injection head 3 is lowered by the drive mechanism, each needle 2 pierces the raw meat 4, and the pickling liquid becomes the raw meat 4 Injected into. The supply source includes a plunger pump 5 and a tank 6, and the plunger pump 5 is connected to the tank 6 and the injection head 3. Then, the pickling liquid is stored in the tank 6, the pickling liquid is sent by the plunger pump 5, the pickling liquid is guided to the injection head 3, and supplied to each needle 2. On the other hand, the drive mechanism is composed of a motor or a cylinder and is accommodated in the housing 7 and connected to the rod 8 and the injection head 3. Therefore, the rod 8 and the injection head 3 are lowered by the motor or the cylinder, each needle 2 is pierced into the raw meat 4, and the pickle liquid is injected into the raw meat 4.

  Further, in this injector, before the pickle liquid is injected into the raw meat 4, the weight of the raw meat 4 is detected and measured by the load cell 9.

  In this embodiment, the feed conveyor 1 is divided into upstream, intermediate and downstream conveyors 10, 11, and 12, and raw material meat 4 is carried in by the upstream, intermediate and downstream conveyors 10, 11, and 12, sent, carried out, and intermediate Each needle 2 is attached to the injection head 3 above the conveyor 11. Furthermore, when the load cell 9 is supported by the housing 7 and the intermediate conveyor 11 is supported by the load cell 9 and the raw meat 4 is placed on the intermediate conveyor 11, the load cell 9 detects the weight of the intermediate conveyor 11 and the raw meat 4 And measured. Further, in this embodiment, motors 13, 14, and 15 are provided in the upstream, intermediate, and downstream conveyors 10, 11, and 12, respectively, and the motors 13, 14, and 15 and belts or rollers are supported by a frame. The belts or rollers are driven by 13, 14 and 15, and the raw meat 4 is carried in, sent and carried out. In the intermediate conveyor 11, the frame, the motor 14, and the belt or roller are supported by the load cell 9. Therefore, when the raw material meat 4 is placed on the intermediate conveyor 11, the load cell 9 receives the weight of the intermediate conveyor 11 and the raw material meat 4, and the load cell 9 detects and measures the weight of the intermediate conveyor 11 and the raw material meat 4.

  Therefore, the weight of the raw meat 4 can be measured easily and accurately.

  Further, when the control device 16 is connected to the load cell 9, the supply source and the drive mechanism, and the pickle liquid is injected into the raw meat 4, the supply device or the drive mechanism is controlled by the control device 16 based on the measured value of the load cell 9. The injection volume is adjusted. For example, when the control device 16 is connected to the load cell 9 and the plunger pump 5 and the weight of the raw meat 4 is large, the plunger pump 5 is controlled by the control device 16 based on the measurement value of the load cell 9, and the feed amount is Increase and the injection volume increases. On the contrary, when the weight of the raw material meat 4 is small, the plunger pump 5 is controlled by the control device 16 based on the measured value of the load cell 9, the feed amount is reduced, and the injection amount is reduced. Further, the injection head 3 is lowered by the motor or the cylinder, each needle 2 pierces the raw meat 4 and the pickle liquid is injected into the raw meat 4. When injected, the injection amount is related to the speed of the injection head 3. To do. The lower the speed of the injection head 3, the larger the injection amount, and the higher the injection head 3, the smaller the injection amount. Therefore, when the control device 16 is connected to the load cell 9 and the motor or cylinder, and the weight of the raw meat 4 is large, the control device 16 controls the motor or cylinder based on the measured value of the load cell 9, and the lowering speed of the injection head 3 Can be reduced and the injection volume can be increased. When the weight of the raw meat 4 is small, the motor or cylinder can be controlled by the control device 16 based on the measured value of the load cell 9 to increase the lowering speed of the injection head 3 and decrease the injection amount.

  Therefore, in the case of this injector, when the pickle liquid is injected into the raw meat 4, the injection amount can be made to be proportional to the weight of the raw meat, and the weight ratio can be kept constant. It is also possible to connect the control device 16 to the operation panel, select the product type by the operation panel and the control device 16, and change the weight ratio depending on the product type. For example, in some products, 20% of the weight is pickle liquid and in other products, 30% of the weight is pickle liquid.

  Furthermore, in this injector, a sensor 17 is attached to the beam 18 above the feed conveyor 1. The sensor 17 is an optical sensor. Furthermore, when the control device 16 is connected to the sensor 17 and the motors 13, 14, 15 and the raw meat 4 is sent by the feed conveyor 1, the position of the raw meat 4 is detected by the sensor 17, and based on the detection signal, The motors 13, 14, and 15 are stopped by the control device 16, and the feed conveyor 1 is stopped. Thereafter, the weight of the raw meat 4 is measured by the load cell 9, the injection head 3 is lowered by the drive mechanism, and the pickle liquid is injected into the raw meat 4.

  Therefore, when the feed conveyor 1 is stopped, the weight of the raw meat 4 is measured by the load cell 9 and the pickle liquid is injected into the raw meat 4. As a result, the weight of the raw meat 4 can be accurately measured, and the pickle liquid can be reliably injected. The raw meat 4 can be continuously fed until the position of the raw meat 4 is detected by the sensor 17. When the raw meat 4 is not sent, the feed conveyor 4 does not stop, the injection head 3 is lowered, and the pickle liquid is not discharged.

  The pickling liquid may be difficult to be injected depending on the physical properties of the raw meat 4 and may be easily injected. However, when the pickling liquid is injected into the raw meat 4, the weight of the raw meat 4 is increased by the pickling liquid. Is natural. Therefore, not only the weight of the raw meat 4 is measured by the load cell 9 before the pickle liquid is injected into the raw meat 4, but also the weight of the raw meat 4 by the load cell 9 when the pickle liquid is injected into the raw meat 4. Is measured, whereby the injection amount of the pickle liquid can be determined. Thereafter, based on the determination result, the control device 16 may control the supply source or the drive mechanism to adjust the injection amount. For example, when the pickling liquid is difficult to be injected and the injection amount is insufficient, the control device 16 then controls the supply source or the drive mechanism based on the determination result to increase the injection amount. On the other hand, when the pickling liquid is likely to be injected and the injection amount is excessive, the control device 16 controls the supply source or the drive mechanism based on the determination result. Can correspond to the weight.

  After the injection of the pickle liquid, the weight of the raw meat 4 is measured by the load cell 9, and the injection amount of the pickle liquid is determined. Thereafter, when the injection amount is insufficient, the injection head 3 may be lowered again to inject the pickle liquid.
