Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus for removing shell sand which can surely and efficiently remove sand to improve the cooking time and the safety of a food. <P>SOLUTION: This apparatus for removing shell sand gives low frequency electric pulses to shells in a state floated in salt water in a tank 1 to stimulate respiratory movements. Thereby, sand can be removed highly efficiently from the shells in a short time. The apparatus also has a circulation system having functions giving oxygen to the shells 13 and simultaneously washing vomited sand and excrements which are guided to a precipitation tank 3. Thus, shells 13 are efficiently separated from the sand and the excrements. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  This invention is invention of the food processing apparatus aiming at the shortening and efficiency improvement of the sand removal process by giving the low-frequency electric pulse to the shellfish from the sand removal performed before cooking shellfish.

  A conventional sand removal device for shellfish is generally performed by spontaneous respiration of shellfish soaked in salt water in a tank tank for a long time.

  However, this method took several hours to a day to complete sand removal. Also, if there are shellfish with weak breathing movement, the sand removal is not performed completely, and it cannot be judged by the appearance that the sand removal is completed.

As a result, shells from which sand removal has been completed and shellfish from which the sand removal has been completed are mixed, which causes problems in cooking and hygiene. This is a major safety and health issue at food production sites or at home. Specifically, it was inevitable that sand, bacteria attached to sand, and bacteria attached to shellfish excreta were mixed. In addition, eating shellfish with incomplete sand removal had a significant adverse effect on the mouthfeel and the mouthfeel when chewing and chewing sand with teeth.

  The problem to be solved is to reliably and efficiently treat sand removal from shellfish, to shorten cooking time and to ensure food safety.

  Applying the principle of the low frequency treatment device used in the human body, the shells are given electrical pulses with a frequency that moves the respiratory muscles of the shellfish. The electric resistance of salt water is low and electric pulses can easily energize shellfish. It has a salt water circulation system to make up for the lack of oxygen and the cleaning of energized shellfish.

  The sand removal apparatus of the present invention is characterized in that a low-frequency electric pulse is energized for a certain period of time to shellfish 13 placed in a basket 4 in salt water in a tank tank 1. This low frequency electric pulse has the effect of causing the shell 13 to breathe muscles and expelling sand quickly. In this apparatus, the shellfish 13 is put in a suspended tub 4 and floats from the bottom of the tank tank 1, and the salt water in the tank tank 1 is circulated by the circulation pump 8 to supply oxygen from the air to the shellfish 13. At the same time as it is supplied, it has a circulation system that cleans the discharged sand and excrement 12 and guides it to the settling tank 3. As a result, the shells 13, sand and excrement 12 can be separated efficiently. As a secondary effect, ions are generated in the salt water by applying a low-frequency electric pulse to the salt water in which the shellfish 13 are immersed. This can be expected to have a sterilizing effect on salt water.

  The tank tank 1, the lid 2, the precipitation tank 3, the basket 4, the electrode 5, the low frequency pulse generation circuit 6, the filter 7, the circulation pump 8, the circulation pipe 9, the oxygen supply 10, and the control device 11 are the basic components. High efficiency was achieved with a simple component structure.

  FIG. 1 is a cross-sectional view of a first embodiment of the device of the present invention, in which shells 13 are housed in a tub 4 and immersed in salt water in a tank tank 1, energized with low-frequency electric pulses, and salt water is circulated. Represents. Since the main body of the invention is the configuration of the tank tank 1, the tub 4, the electrode 5, and the circulation system, description of water supply / drainage, low frequency frequency, and power source is omitted. The flow of sand, excrement 12, air (oxygen), and salt water is indicated by arrows.

  The shells 13 are arranged so as not to overlap the trough 4 suspended in the tank tank 1. The salt water surface should be soaked with shellfish 13. A low frequency pulse for moving the respiratory muscles of the shellfish 13 is energized from the electrode 5 in the tank tank 1 brine. The sand and excrement 12 discharged from the shellfish 13 all at once are urged by the circulating water from the basket 4 and move to the sedimentation tank 3. The salt water in the supernatant of the sedimentation tank 3 is supplied with oxygen 10 from the air by the circulation pump 8, and is supplied again to the salt water in the tank 4 through the circulation pipe 9.

  It is effective for sand removal of edible organisms that may contain sand and foreign substances, not limited to shellfish. If an ultrasonic cleaner is used in combination, cleaning can be performed at the same time. Ions are generated in salt water by applying low-frequency electric pulses to salt water immersed in shellfish. This can be expected to sterilize the circulating salt water and prevent the food poisoning peculiar to shellfish. Efficiency can be improved by installing a heater in the tank tank or circulation path and controlling the temperature of salt water at a constant temperature.

It is explanatory drawing which showed the implementation method of the sand removal apparatus of shellfish. (Example 1)
