EA045488B1 - AUTOMATED DEVICE FOR PRODUCTION OF PANCAKES AND PANCAKES - Google Patents

Description

Technical field

The invention relates to equipment for the baking industry, namely to the design of an automated device for the production of pancakes and pancakes and can be used in large- and small-scale production of pancakes and pancakes.

State of the art

Various designs for the production of pancakes and pancakes are known from the prior art. For example, a machine for making pancakes and pancakes is known, containing first, second and third horizontal drive rolls, the first having a larger diameter and located next to the second, located in a gap with the third. The first has a smooth surface and is a heated cooking roller. The other two rotate in opposite directions and their lower parts are immersed in a container of batter. The third roller has a recess at its periphery to shape the batter passing through the gap (US patent US 3814006, published 06/04/1974, IPC: A21B5/00).

Removing food at the end of cooking requires special precautions because the roller is not smooth and the scraper may not be in contact with it throughout the entire rotation cycle. Thus, it is necessary either to provide an additional mechanism, driven by cams, to automatically control the raising of the scraper at the end of a cycle and its lowering at the beginning of the next cycle, or, in the absence of such a mechanism, to ensure continuity of the supporting surface for the scraper by connecting the relief elements of the surface with connecting stripes. However, this last solution makes it necessary to separate the resulting pancakes from each other by cutting the connecting strips.

A device is known for applying a cooking mixture to a rotating cooking drum of an automatic machine for preparing pancakes and pancakes using a continuously rotating paste-entraining roller, partially immersed at a constant depth in a mixing tank. In this case, the film of the mixture is carried away due to adhesion to the surface of the roller and contact with moving means for partial retention of this film (US patent US 3978781, published 09/07/1976, IPC: A21B5/00).

The disadvantage is that the mixture is gradually heated, which allows the device to work only for a short time; the machine has to be moved from the working position to the standby position, which reduces the amount of finished product obtained.

A device for making pancakes is known, including a bunker for dough, a frying table driven by a Maltese mechanism, a heater, a spreader, a turner, a remover, as well as additional drives of these mechanisms. The remover includes a pusher/shifter, and the frying table is made up of sections, representing a circular sector or part/fragment thereof, or from groups of such, made with the possibility of independent adjustment of their relative position (RF patent RU 2588461, published on June 27, 2016, IPC: A21B5/03).

The disadvantages of this device are its large dimensions, complexity of execution, necessary line maintenance regardless of the wear of the actuators, and a large number of mechanized components, which increases the complexity of equipment maintenance.

The essence of the invention

The objective of the invention is to create a simple device for the automated and continuous production of pancakes and pancakes of the required size and shape.

The essence of the invention is an automated device for the production of pancakes and pancakes, containing a supporting profile frame on which a ring oven is installed, a device for automatically feeding dough to the oven tray and a receiving conveyor for the finished product. The annular furnace contains a heat-insulating body, inside of which an annular hearth is installed vertically with the possibility of rotation around its central horizontal axis. To retain warm air, the hearth contains side walls in the form of metal sheets; a gas burner nozzle is installed inside the hearth space. The device for automatically feeding dough onto the oven floor is located under the oven floor and contains a bowl for liquid dough, in which cups for feeding the dough onto the oven floor are located. The cups are mounted on an axial shaft, on which one pair of disks is also installed to transmit the rotational motion of the hearth to the axial shaft through a friction transmission.

The essence of the invention is also that the annular hearth is mounted on two single-flange wheel pairs with a drive, which are located in the lower part of the annular hearth, and the axles of the wheel pairs are located on bearings mounted on the supporting frame housing.

The essence of the invention is also that the gas burner is installed on a heat-insulating body, and the gas burner nozzle is located vertically upward in the working space of the hearth.

Claims (1)

In fig. Figure 5 shows a general view of the device for automatically feeding dough into the oven. In fig. Figure 6 shows a longitudinal section of a device for automatically feeding dough into the oven from the front side. Carrying out the invention The automated device consists of a supporting profile frame (1), on which the following components are installed: an annular under (2), a body (3) with thermal insulation protection, a device (4) for feeding dough to the oven under (2) and a receiving conveyor (5) of the finished product. product. The body is made in the form of metal structures, between the walls of which there is a layer of heat-insulating material (6). A mount (7) for installing a gas burner (8) is mounted on the body. The oven hearth (2) is made of a special grade of metal, food steel, which is specially prepared for the ring hearth. The annular hearth (2) is processed with special equipment for smooth operation, that is, without beating and without deviation of the hearth to the side relative to the central axis. In a preferred embodiment, the rotation of the hearth (2) is carried out by means of a cylindrical external friction gear, which is designed to transmit rotational motion using the friction force between the wheels of the friction mechanism. As shown in FIG. 1, 2 and 4, the friction transmission is made in the form of two single-flange wheel pairs (9), which are located on opposite sides in the lower part of the annular hearth, and the axes of the wheel pairs (9) are located on bearings mounted on the body of the supporting frame (1). On single flange wheelsets (9) a furnace ring under (2) is installed and, under the influence of friction force arising from the weight of the furnace hearth, the rotation of the wheelsets (9) is transmitted to the hearth and the ring under (2) rotates inside the furnace. The flanges (10) of the wheels serve for the correct direction and operation of the annular hearth of the furnace. The rotation of the axis of one wheel pair (9) is carried out by an external drive (11) (geared motor), and the rotation of the second wheel pair is carried out by means of a chain transmission from the first wheel pair. Note that other methods of transmitting motion from wheel pairs to the hearth are also possible, for example, through a gear drive. Other design solutions for rotating the furnace hearth are also possible. It is possible to adjust the speed of rotation of the hearth due to the installed frequency converter to synchronize the operation of all components. Metal sheets (12) are installed on the sides of the hearth (2) to retain warm air and to maintain heating of the furnace hearth (2). They are attached to the inner rings (13) of the furnace bottom with bolts and nuts (14). The sheets themselves have windows, which are covered with overhead valves (15), and which are used to regulate the air supply and the removal of combustion products. Combustion products are evacuated from the working space of the annular furnace through the gas outlet channel (16). The dough piece enters the ring tray automatically; the dough piece is fed by a special device (4) for feeding the dough. The mechanism of the device consists of a bowl (17), into which batter is poured for the production of pancakes or pancakes. In liquid form, the dough is fed to the oven using feeding cups (18). The cups are mounted on an axial shaft (19), on which one pair of disks (20) is also installed, transmitting movement to the axial shaft from the rotation of the furnace hearth (2) through a friction transmission. Due to the temperature, the liquid dough sticks to the outside of the rotating hearth (2) of the oven, which carries the stationary dough piece. The exit of the finished product occurs automatically; the finished product is removed from the bottom web by a special scraper design (21) and enters the receiving conveyor (5). The nozzle (22) of the gas burner (8), installed on the heat-insulating body, is located vertically in the working space of the hearth, with the nozzle outlet hole under the hearth ring. This arrangement of the nozzle (22) is most effective for heating the hearth ring. An automated device with the output of the finished product frees up a large number of service personnel, facilitates the working conditions, labor and maintenance of the furnace. In the example of a specific design, the diameter of the hearth (2) is 1200 mm, the width of the hearth blade is 600 mm, and the hearth rotation speed is 2-10 rpm. The volume of the bowl is 50-70 l, the number of serving cups (18) is four, a pair on each shaft. However, the dimensions given, as well as the number of cups, may vary depending on the problem being solved. For example, in the case of small-sized pancakes, the number of cups can be greater, for example, four on each shaft, that is, eight. In the case of larger pancakes, the number of cups is reduced and can be made up to one rotating cylinder for baking a continuous layer of pancakes. Also, the shapes of the cups can vary depending on the desired shape of the pancakes: round, elliptical, rectangular, triangular, etc. CLAIM 1.
