The Pyongyang Grain Processing Machine Factory has made a modern wheat processing machine.

“In early February, a consultative meeting was held to manufacture wheat processing equipment with a capacity of thousands of tons. In fact, the factory’s foundations were poor, and it was not easy to make a decision on manufacturing the unfamiliar machine while carrying out the factory’s quota under the national economic plan. At that time, the speech made by a leading official of the Ministry of Procurement and Food Administration, attending the meeting, touched our heartstrings,” said the factory’s general manager, recalling those days.

This factory, a machine-building unit in the sector of procurement and food administration, is faced with the task of providing the people with quality processed wheat as soon as possible, explained the official from the ministry, calling on the workers of the factory to find a way with a determination.

There can be no other option and we should not import it, but make it by our own efforts–this was a unanimous opinion of those attending the meeting. 

A campaign was launched to make the machine.

The factory gave precedence to the supply of materials needed for the manufacture of the machine on the basis of the design completed by the Grain Processing Institute under the Ministry of Procurement and Food Administration, and encouraged the employees to present technical conceptions for making a wonderful one with less cost.

As a result, problems that were thought to be difficult were solved one by one, and the making of an efficient machine was pushed forward.

But, many difficulties arose.

It was a generally accepted idea that vibrating motor should be installed on stone separator in the grain cleaning process. The problem was that most employees thought that this vibration motor could not be produced by the factory.

“We could not tolerate it,” said senior engineer Ri Su Jin. “Technicians and skilled workers of the factory pooled their wisdom with researchers of the Grain Processing Institute, and found a way of solving the problem.”

They changed designs for more than 20 days and changed their motors with different capacities, thus finally making a stone separator.

Such spirit was also displayed in the days of making a roller mill.

According to the design, the mill frame was to be made by casting. At that time, the factory was repairing the medium-frequency induction furnace, and had to wait 40 days to get necessary casting.

The factory decided to make the frame with iron plate without waiting for conditions to be created. In the case of steel sheet, several problems had to be solved, including vibration, noise and sealing.

But the skilled workers of the factory, based on their rich experience, found a reasonable way of manufacturing the frame with iron plates and presented an innovative way of adjusting the axis of the driving roller.

In the final analysis, the roller mill frame revealed its impeccable appearance in more than ten days.

“Our own efforts produced novel ideas and, as a result, a modern wheat processing machine, of which we can proud, was successfully made,” said the manager.

The machine was installed at the Pakchon County Food Administration Station.
