Method and device for treating waste bread

Abstract

Provided is a method and device that can efficiently crush and dry waste bread into fine powder particles with low moisture content so that they can be used as compound feed for livestock. The waste bread (A) is supplied into the primary drying passage (1) which has a rotary grinding blade (2b) and a hot air nozzle (3a) with an outlet facing the delivery direction, and is dried using the front end surface of the rotary grinding blade (2b) and the primary drying passage (3a). The inner bottom surface of the passage (1) grinds and pulverizes the waste bread (A). At the same time, the heated primary drying passage (1) and the hot air sprayed from the nozzle (3a) are used to evaporate and remove the moisture in the waste bread (A). It is then finely pulverized by the rotating blade (20) and supplied into the secondary drying passage (4) through the mesh body (7a), and then dried in the secondary drying passage (4).

Description

technical field [0001] The present invention relates to a method and apparatus for disposing of waste bread, which can dispose of bread produced due to production loss in the manufacturing process, bread discarded after being sold in stores, bread crumbs produced during cooking or leftovers, etc. The discarded bread is pulverized and dried to form a granular body that can be used for livestock feed and the like. Background technique [0002] In recent years, with the development of the catering industry, the amount of food waste discharged from enterprises has been increasing. In order to limit the increase of food waste and protect the global environment, the Food Recycling Law was implemented in May 2001, which stipulated that the recycling rate Raised to a minimum of 20%. [0003] In addition, the consumption of bread has been increasing year by year due to changes in Japanese eating habits. Along with this, in addition to the leftover bread crumbs provided by the above-...

AI Technical Summary

Problems solved by technology

[0006] However, although the above-mentioned system can process waste bread and bread crumbs together with other kitchen waste generated from households, it cannot only treat waste bread and bread crumbs in large quantities, and its treatment process is also complicated and cannot be effectively processed. The processing of discarded bread and bread crumbs etc. (hereinafter referred to as discarded bread) discharged in large quantities as described above is performed efficiently, and a method for effectively processing discarded bread is desired.
