Description

  The present invention relates to an ice making vehicle that can be moved by mounting an ice making device on a trailer or the like.

  Japanese Unexamined Patent Application Publication No. 2004-44850 discloses a mobile ice making device in which a harvest ice making device is mounted on a moving vehicle such as a trailer. This device moves to a ski resort or event venue to produce ice or artificial snow.

The harvest ice making device used in this device is a flat ice making plate that is cooled by a refrigerant, installed in a vertical or inclined manner, and water is allowed to flow from the top of the ice making plate to produce an ice layer on the ice making plate. Let When the ice has reached a certain thickness, the refrigerant is switched to the heating medium and peeled off from the ice making plate.
The peeled plate-shaped ice falls on the corrugated chute, is crushed by the impact, is sent to the rear of the vehicle by a screw conveyor, and is discharged outside the vehicle. If you want to get fine snow, crush the ice pieces with a crusher installed behind the trailer.

  In Japanese Patent Application Laid-Open No. 2004-44850, in order to increase the area of the ice making plate group mounted on a narrow trailer, the ice making plate group is arranged in parallel in a direction perpendicular to the traveling direction of the vehicle. Although not specified in the specification of the application, it is presumed that the number of ice plates can be increased by increasing the vehicle length.

  JP2004-44850

  Crushed ice produced from ice blocks and the like is an important coolant for maintaining the freshness of freshly caught fish. For this reason, in a large fishing port, 135 kg of ice cubes are manufactured at a nearby ice making factory, and are crushed into pieces of ice having a size of several centimeters and supplied to exchanges, distributors, processing factories and the like. A small fishing port with no room to build an ice factory is transported by trucks.

  The peak season of fishing at fishing ports is generally concentrated in 3 to 4 months, and freshly caught fish must begin cooling immediately. Therefore, the production of ice cubes is started from the off-season when the catch is predicted, stored in a warehouse, and delivered to an exchange or the like at the time of landing.

  However, the actual catches fluctuate greatly, causing excessive and shortage of ice storage, which is a factor that increases costs. In particular, when there is a shortage, ice cubes must be purchased and delivered from a remote ice factory, and supply to small fishing ports with low demand is forced to be extremely expensive.

  If mobile ice trucks can be used for these small fishing ports and crushed ice can be produced locally, it is not necessary to store excess inventory, and it can be easily supplied when inventory is insufficient. There is a possibility that excessive inventory and wasteful transportation costs can be reduced, and delivery time can be easily met.

  However, since the conventional mobile ice making apparatus does not have facilities for storing crushed ice, the produced crushed ice must be immediately transported to the ice storage warehouse of the customer. Therefore, the ice making with the mobile ice making device is limited to the time during which the operation of receiving the crushed ice can be carried out. Therefore, it must be stopped at night or on holidays, and the operating rate of the apparatus is very low.

  As for the quality of the crushed ice produced, the crushed ice that has just been crushed by the impact dropped from the ice making plate onto the chute has a large variation in size and shape, and tends to hinder handling and transport.

  The problem of the present invention is a mobile ice making vehicle that moves to a small fishing port where construction of an ice making factory is not easy and produces ice crushed ice for cooling fresh fish. The operating rate of ice making equipment is high, and there are few variations in size and shape. It is to provide a mobile ice maker that produces crushed ice.

  Claim 1 of the present invention is an ice making vehicle in which a cooling tower, an air conveyance device, an ice storage, a refrigerator, and a harvest ice making device are mounted on a vehicle such as a trailer. An ice breaker outlet is provided on the rear end side of the vehicle, and the ice making plate train in the ice making device is arranged in parallel with the traveling direction of the vehicle to receive ice falling from the ice making plate below the ice making plate. A moving ice-making machine equipped with an inclined plate leading to the ice breaking outlet and an ice breaker installed between the end of the inclined plate and the outlet. It is a car.

  A second aspect of the present invention is a mobile ice maker in which the refrigerator and the ice storage in the first aspect are mounted on the vehicle front side close to the ice making machine harvest ice making machine.

  A third aspect of the present invention relates to the first and second aspects, wherein the air conveying device includes an ice breaker receiving hopper, a stirring rotor, a screw feeder, and an ice breaker discharge pipe. It is a mobile ice truck that is transported from

  A fourth aspect of the present invention provides the air blowing device according to any one of the first, second, and third aspects, wherein the air blowing device is a receiving and stirring unit such as an ice breaker receiving hopper, a stirring rotor, and a screw feeder; It is a mobile ice maker that is divided into two.

Action and effect of device

  The mobile ice making machine of the present invention moves to a small fishing port or the like where an ice making factory is not installed, lowers a cooling tower and an air conveyance device, and manufactures ice breaks. Therefore, these devices do not need to specify the mounting position on the vehicle, and may be located at any place. It is also mounted on a trailer so that it can be loaded and unloaded.

The cooling tower lowered from the top of the vehicle is connected to the refrigerant pipe of the ice making device and used to cool the refrigerant. On the other hand, the air conveyance device is installed adjacent to the discharge port at the rear end of the vehicle, and the position is adjusted such that the crushed ice discharged enters the ice crushed receiving hopper of the air conveyance device. The discharge pipe of the air transfer device is connected to an ice breaker transfer pipe to an ice storage warehouse when it can be received at a demand destination, and to a transfer pipe to an ice storage on a trailer or the like at night when it cannot be received.
After making these preparations, the ice making device is started.

  The raw water flowed from above the ice making plate repeatedly freezes and peels, and the peeled plate ice falls onto the inclined plate, is roughly crushed, slides down and enters the ice breaker. It is crushed into small pieces with few variations of about several centimeters by an ice breaker, and is directly put into the ice breaker receiving hopper of the air conveyance device from the discharge port.

  The reason for installing the ice making device at the rearmost part of the vehicle and providing the ice breaking discharge port at the rear end of the vehicle is to put the ice breaking into the ice breaking receiving hopper of the air carrier without installing a screw conveyor in the vehicle. . As a result, the installation space for the ice making plate can be increased.

An inclined plate with a downward slope is installed toward the discharge port. The reason for installing the ice making plate in parallel with the traveling direction of the vehicle is to smoothly slide the falling plate ice on the inclined plate. When arranged at right angles to the traveling direction, the ice from the downstream ice making plate falls on the ice falling from the upstream ice making plate, preventing smooth crushing and sliding off.
Further, the surface of the inclined plate does not need to have a special shape such as a corrugated shape, and a sufficient ice breaking effect and sliding property can be obtained by the smooth plate.

  The ice that has slid down is crushed by an ice crusher, becomes crushed ice with little variation in size and shape, and enters the ice receiving hopper of the air conveying device from the discharge port.

  The raw water that could not be frozen on the ice making plate falls into the raw water tank installed below the inclined plate and is reused as raw water.

  The refrigerator is for cooling the refrigerant of the harvest ice making device, and a refrigerant circulation pipe is connected between the ice making plate and the refrigerator. In order to shorten the piping as much as possible and reduce heat loss, it is desirable to mount the refrigerator in a location close to the ice making device.

The air conveyance device includes an ice breaker receiving hopper, an agitation rotor, a screw feeder, and a rotary valve for agitating and supplying the crushed ice, and a blower and a blower pipe for delivering conveyance air.
The crushed ice that has entered the crushed ice receiving hopper from the ice machine outlet is sent to the rotary valve by the screw feeder while being agitated by the agitating rotor, supplied to the blower pipe, and air-delivered from the outlet to the ice storage warehouse of the customer Is done.

  Ice making is also carried out at night or on holidays when the customer cannot receive the crushed ice, and the crushed ice is transferred to the ice storage and transferred to the customer's warehouse after the next day. This greatly improves ice making capacity.

  Since the air conveying device is used after being lowered from the vehicle, it is mounted at any place where there is no hindrance to loading and unloading. In addition, since the agitation rotor, screw feeder, rotary valve, blower, etc. each require a drive motor, the size of the equipment tends to increase as a whole. If it hinders loading or unloading, it should be divided into ice receiving hopper, agitation / feeding unit, transporting unit, etc., and assembled into an integrated facility at the destination.

  The place where the ice storage is mounted is preferably a location close to the ice making device in order to shorten the ice breaking conveyance distance from the air conveyance machine.
