Some grain dryers have problems in terms of safety, reliability, and adaptability. The Shandong Provincial Department of Agriculture and Rural Affairs requires rectification within three months.

It is reported that the scope of the grain dryer survey is 11 cities including Jinan and Heze. The survey objects are selected from users who purchase and use continuous and circulating grain dryers with a working season and enjoy subsidies for agricultural machinery purchases from 2015 to 2017. A total of four models of four consecutive companies and 12 models of 12 companies in circulation were investigated, involving 80 users. The survey adopts the method of user satisfaction evaluation, and the user evaluates the five levels of satisfaction of the four contents of the product safety, reliability, applicability and after-sales service status.

The survey results show that the user has a good comprehensive evaluation of the grain dryer. The product satisfaction index reaches 90 points or more. The products are produced by Linyi Jinming Machinery Co., Ltd. 5HP-15 circulating dryer and Shandong Shuangli Modern Agricultural Equipment Co., Ltd. 5HL-120 continuous dryer, 5HXG-15 circulating dryer produced by Zhengzhou Xinguang Mining Machinery Manufacturing Co., Ltd., 5HCY-30 circulating dryer produced by Anhui Chenyu Machinery Technology Co., Ltd. and Shanghai Sanjiu Machinery CPR-165 circulating dryer produced by the company. But there are also four major problems.

In terms of safety, some products have more safety signs missing, and safety protection is not in place. The main performance is the poor quality of the safety signs, easy to fall off or missing, etc., not in accordance with the provisions of the protection, the transmission sprocket, pulleys and other exposed transmission, rotating parts without protective cover or defect, failure and so on. In terms of reliability, some products have poor quality parts and problems with the quality of heat source devices. The specific performance is that the motor and fan motor damage is serious, the slag chain is broken, the control cabinet power switch is damaged, the full grain alarm is out of order, the grain speed motor speed controller is insensitive, the temperature sensor is not accurate, the hot stove or the furnace core exists. Quality issues, etc. In terms of adaptability, users report that some products do not meet the requirements of the company's explicit value, precipitation capacity and drying operation quality, the effectiveness and sensitivity of electrical control, and the applicability of the matching motor. In terms of after-sales service, some enterprises have not received timely after-sales service, poor performance of service commitments, insufficient supply of product parts, and poor ability of on-site personnel to solve problems on site.

Feng Zhonghua said that in response to the problems found in the investigation, the next step will be to send a one-to-one rectification notice to the involved manufacturing enterprises, and the rectification period is 3 months. The results of rectification of production enterprises in Shandong Province must be confirmed by the competent department of agricultural machinery in the city where the enterprise is located. The results of rectification of enterprises in other provinces must be confirmed by the competent department of agricultural machinery in the province. After receiving the rectification notice, the enterprise refuses to rectify or fails to meet the rectification requirements. It is recommended that the relevant agricultural machinery appraisal agency cancel the agricultural machinery promotion appraisal certificate of the product in accordance with relevant regulations.
