A limitation of this electric waffle iron is the scarcity and high cost of food-grade aluminum matrix material and the use of technically and economically imperfect mica plastic heater and its electrical control.

The objective of the proposed utility model is to increase the efficiency, reliability and quality of the device by optimizing a number of structural and electrical elements.

Utility Model Disclosure

The technical result achieved is to increase the efficiency, reliability and quality of the device by optimizing a number of structural and electrical elements, namely: in an electric waffle iron, consisting of a housing, a thermal chamber, thermoregulating electrical equipment, auxiliary elements (two half-matrixes are part of the thermal chamber with dough processing surfaces and electric heaters), matrix half-molds are cast from cast iron used in the food industry as an electric For electric heaters, flexible electric thermal cables are used, fixed over the area of half-form matrices, the electrical equipment additionally contains power and time controllers.

Thermal cables in an insulating and heat-resistant jacket are laid in matrix half-forms in gutters made in the shape of a flat spiral. The pitch of the spiral depends on the specific conditions, averages 19 ... 21 mm and is determined by the calculated optimizing program.

As part of the auxiliary elements, the electric waffle iron additionally contains a container for batter, a filling mechanism for the dough, and a waste collector with

pallet, as well as a freely movable remote control for electrical equipment. The power regulator of the heaters is assembled on a controlled seven-cell.

The figure shows two basic (square and round) forms of matrices with spiral laying of thermal cables.

Utility Model Implementation

An electric waffle-iron consists of the following elements: flexible thermal cables-electric heaters 1 half-matrices 2, and also not shown in the figure, a frame, a container for liquid dough, a filling mechanism (feeder) for a dough, a waste collector with pallets of a feeder, and a moving panel for electrical equipment.

In the manufacture of units in contact with the test, used corrosion-resistant materials that are approved for use in the food industry.

The thermal chamber consists of a lower stationary and an upper 90 ° matrix rotated by a hinge. The matrices are made of cast iron castings and are heated by a flexible thermal cable, which provides a uniformly distributed operating temperature of about 200 ° C with an accuracy of 1 ° C. The upper matrix has a special lock, which allows you to mechanically lock the matrix at the time of baking the dough. The counterweight mounted on the upper matrix facilitates its lifting to a vertical position. The feeder of the dough filling mechanism has an axis with a dosing bath on the levers, with the help of the handle a portion is collected from the dough container.

The heat chamber power regulator is assembled on a controlled seven-cell, which allows you to smoothly change the alternating voltage supplied to the thermal cables from 0 to 220 V.

Preparing for work.

To establish a sanitary-prepared electric waffle-iron on a working site. Open the upper matrix and, putting the level on the lower matrix, achieve, using the adjusting bolts on the legs of the frame, the minimum deviation from the horizontal of the matrix surface. Install the control panel to the right or left of the frame. Ground the frame and control panel. Connect the remote to the network. Lock the heat chamber and turn on the heating to burn the dies for 60 minutes at a temperature of 150 ° C. Open the heat chamber, remove scale and grease the upper and lower matrices with food paraffin, working temperature 180 ° С, cycle time 20 ... 30 sec. The operation to saturate the working surfaces of the matrices with fat is carried out repeatedly with cleaning the matrices from the stick.

Using power regulators, a timer, a temperature regulator to choose the optimal baking modes.

Operating procedure.

- Turn on the power on the remote control. Set the operating temperature to 175 ... 180 ° C and the timer cycle time 20 ... 30 sec.

- Prepare the dough and pour into the container. When entering the heat chamber mode, dial the dose of the test with the feeder and fix the axis with the feeder bath for 30 seconds on the capacity catcher.

- Turn on the timer toggle switch.

- Open the heat chamber and grease the matrices. Using the handle of the feeder, raise the dough tray to the center of the matrix and pour it onto the surface. Lower the bath in the container with the dough and lock the heat chamber. Raise the tray with the dough and fix it in the container catcher.

- Using the sound and light signals from the control panel, open the heat chamber and remove the wafer cake. Clean and grease the matrices, repeat the cycle.

- Maintain the dough in the container at the required level and replenish in a timely manner.

- Monitor the temperature conditions of the heat chamber; in case of failure, stop baking.

- At the end of work, turn off the power, remove and rinse the container with the dough. Clean dies, waste bin and trays.
