Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a reversing feed device for a lifting machine.

Prior Art and its Problems An automatic frying machine is used as a device for manufacturing fried foods, such as tempura, using materials mainly made of minced fish meat. This automatic frying machine is equipped with a transfer means such as a net conveyor that feeds food materials formed into a desired shape into an oil tank filled with edible oil and heated, and that sequentially transports the food materials. has been done. The articles are then transported through the oil tank by being sandwiched between upper and lower conveyors, which are disposed along almost the entire length of the oil tank so that the articles are immersed in the oil in the oil tank. In this case, it is necessary to lengthen the oil tank or slow down the transfer speed, which increases the size of the equipment or limits production capacity. In order to improve this problem, two or more upper and lower transfer lines are formed in the oil tank, and a reversible transfer means is provided in which the articles are sequentially moved in the longitudinal direction of the tank from the bottom to the top. An example of this is Utility Model Publication No. 59-8646, which is related to the applicant's earlier application. This system has two upper and lower transfer lines formed by a combination of three net conveyors in the oil tank, and above these a transfer line using a paddle mixer. Suitable for all uses. However, in the case of thin products, such as flat tempura, the product may not be reliably inverted at the inverting section of the curved line of the net conveyor and at the feeding section to the paddle mixer.

In view of this, it is an object of the present invention to reliably invert thin products such as flat tempura and to prevent bubbles generated in oil from affecting products in the upper transfer line.

Means for Solving Problems The present invention comprises a first stage conveyor disposed at the bottom of the oil tank in the longitudinal direction of the tank, and a second stage conveyor disposed above the conveyor with an interval for transferring the product.
a third bar-type conveyor adjacent to the end of the first-stage conveyor and curved so as to surround the outer periphery of the second-stage conveyor;
After the product is transferred down the downward transfer line by this third conveyor and inverted again, the product is transferred to the paddle conveyor disposed above the second stage conveyor and transferred downward and upward while the inverted position is in a stable position. A baffle plate is installed between the lines to prevent the effects of water bubbles generated and floating from the lower line from affecting the products in the upper line, and this ensures that even thin foods such as flat tempura are kept front and back when transferred through oil. Since it can be reversed, the finish will be beautiful and the color will be more glossy.

Embodiments The present invention will be described below based on embodiments shown in the drawings.

In the figure, reference numeral 1 denotes an oil tank having the size, particularly the length and depth necessary to heat the fried foods sufficiently and to automatically produce multiple products at once.A burner B is installed at the bottom of this oil tank 1. Install the tempura oil in the oil tank and heat it to the appropriate temperature. Further, a conveyor device 2 is disposed at the inner bottom of the oil tank 1 for transporting product materials such as fish paste, korotsuke, and side dishes through the oil. This conveyor device 2 has two endless conveyors (nets, etc.) disposed above and below each other at a required interval depending on the size of the fried product G. The space between the bottom surface of the second conveyor 2b and the bottom surface of the second conveyor 2b is used as a product passageway,
Each is driven in the same direction in synchronization. At this time, the product G introduced from one end of the conveyor device 2 is made to have at least the surface fried by the time it reaches the other end of the conveyor device 2, to prevent it from adhering to other products, and to float in the oil. The total length of the conveyor can be determined by the conveyor, or even if the length of the conveyor is determined, its driving speed can be adjusted as a variable type. In this way, the fried food product is transferred from the starting end of the oil tank to the other end while being immersed in oil. At this time, the floating force of the product is suppressed by the upper conveyor, that is, the second stage conveyor 2b. When the product is transferred to the end of the first stage conveyor, it is then reversed at the end of this conveyor 2a and transferred to the upper transfer line. A third conveyor 3 is provided to ensure that the products at the end of the conveyor device 2 are turned upside down. This third conveyor 3 is opposed to the terminal end of the first stage conveyor 2a at one end thereof,
The product G is curved at a required distance from the outer peripheral surface of the end of the second stage conveyor 2b, and the product G transferred between the first and second stage conveyors 2a and 2b is transported from the end of this conveyor. 2nd stage conveyor 2b
It is transferred between the upper surface side (return side) and the lower surface side of the third conveyor 3 while being reversed along the edge of the second stage conveyor. The distance between the end of the first stage conveyor and the end of the third conveyor should be smaller than the thickness of the product G, and the distance between the end of the second stage conveyor and the end of the second stage conveyor should be made smaller than the thickness of the product G, and the distance between the end of the first stage conveyor and the end of the third conveyor should be smaller than the thickness of the product G, and the distance between the end of the second stage conveyor and the end of the third conveyor should be smaller than the thickness of the product G. The distance between the third conveyor is set to be the same as the distance between the first and second stage conveyors on the forward path side. The third conveyor 3 is a short conveyor 3 parallel to the upper surface of the second stage conveyor, so that the distance over which the inverted product G is transported while its posture is almost stable is parallel to the upper surface of the second stage conveyor. 2b is a net conveyor, whereas this is made up of a number of bars placed horizontally between two opposing endless chains at a fixed pitch smaller than the thickness of the product G, and this bar conveyor ensures that the product is delivered securely. This will promote a reversal.

After the inverted product G is stabilized in its posture after being inverted on this third conveyor 3, it is then transferred to a paddle conveyor 4 arranged at a fixed pitch above this second stage conveyor and submerged in oil in an oil tank. It is transported by floating and sinking. When the product G is transferred by this paddle conveyor, the product G is transferred between the lower transfer line, that is, the first and second conveyor. A baffle plate 5 is inserted between the forward and return sides of the second-stage conveyor 2b and fixed to the frame on the lifting machine side so that no positional deviation occurs from the regular transfer line. The width and length of this baffle plate 5 are such that when the product G is transferred through the lower transfer line while immersed in oil,
The moisture in this product is heated to oil temperature and steam is generated, which appears as water bubbles, but the rising water bubbles should be defined along with their cross-sectional shape so that they do not hit the product on the upper transfer line. It is something. Therefore, the water bubbles generated from the product on the lower line hit the baffle plate, move to the side of this plate, and escape from the side edge of this plate to the upper oil level.

After passing through the lower transfer line and being inverted on the third conveyor 3, the product G is stabilized after being inverted on the horizontal part of this third conveyor, and then is placed above the oil level at a position away from this conveyor 3. However, since a paddle conveyor 4 is disposed at this position, the object is further transported by this paddle conveyor. In this paddle conveyor 4, the product is transferred by floating up and down in the oil by floating on the oil surface and being pushed down by the paddle, so that the product is fried evenly on both sides.

Effects of the Invention According to the present invention, the terminal end of the net conveyor is prevented from curving by using a guide rail, etc., compared to the conventional method, and the contact area and pressure contact between the conveyor and the guide are reduced, so that the net In addition to reducing wear and tear on the conveyor and prolonging its life, a third bar conveyor is provided in the product reversing section to ensure that thin products can be reliably and easily reversed. When the product is in a stable position, the paddle is used to further transfer the product, so the finish on the front and back of the product is uniform.Also, since a baffle plate is installed between the lower transfer line and the upper transfer line, the lower line Since the products on the upper line are not affected by the water that comes to the surface from the products on the upper and lower lines, the advantage is that the products on both the upper and lower lines can be automatically fried while being transferred without damage. There is.
