Description

Pastry vending machine

Technical Field

The invention belongs to the technical field of food vending equipment, and particularly relates to a pastry vending machine.

Background

In canteens of units such as schools, factories and companies, the flour spots are sold by manpower, and the sold flour spots mainly comprise blocky or ellipsoidal objects such as steamed bread, steamed stuffed bun, steamed roll, eggs and the like. In order to save labor cost, improve vending efficiency and standardize the canteen pastry vending process, related vending equipment is required to assist or automatically vend the pastry.

At present, the manually sold pastry is mainly placed in a whole box or a steaming tray, and meal discharging is mainly completed manually, so that the pastry is large in occupied space and time-consuming and labor-consuming. In the patent of application numbers CN202120070361.9 and CN201910262156.X, a multi-layer frame type structure is adopted to place steamed bread trays and other placing devices, and then the pastries are placed on the steamed bread trays; however, in the two structures, there is a defect that automatic meal delivery of steamed bread, for example, in cn201910262156.X, a scraping rod is driven by a chain to push a whole row of flour spots to deliver, so that single flour spot meal delivery cannot be completed, and in the case of soft waxy flour spots such as steamed bread, steamed stuffed bun and steamed roll, the problem of adhesion between the soft waxy flour spots cannot be solved, blockage and accumulation of flour spots are easy to occur in the meal delivery process, the meal delivery fluency of the flour spots is greatly reduced, and the overall meal delivery efficiency of the flour spots is seriously reduced.
