产品介绍
Product Introduction
SDG系列料斗式塑料干燥机是我厂于八十年代初期引进国外先进样机消化吸收，并经过长达十多年的生产改进，现已为成熟产品。全系列产品16只规格，适用于与各种塑料注射、挤出成型机配套使用。全系列产品于90年获轻工部优质产品称号。
SDG series hopper plastic dryer now has become a mature product based on the digestion and absorption of model machines introduced by our factory in the early eighties and with more than a decade of production improvement. There are 16 specifications of products for complete series, applicable to use with the injection of various kinds of plastics and extrusion molding machines. The complete series products obtained the title of Quality Product of Ministry of Light Industry in 1990.
特点
Characteristics
◆ 设备结构简单，无需占地，简化操作流程，节省人力，易于实现自动化；
◆ The structure of the equipment is simple. It does not need to land on the ground, for which the operational process is simplified and manpower is saved to facilitate the achievement of automation;
◆ 原料干燥后，无需反复搬运，不易带入灰尘等污物，同时提高制品质量；
◆ After dried, the raw materials do not need to transport repeatedly, and dust and other dirties are not easy to carry in, at the same time, the product quality is improved;
◆ 原料在干燥料筒中停留时间短，不易变色，同时易于原料干燥后含水量的检测和控制；
◆ The residence time for raw materials in barrel is short. It is not apt to change colors, but at the same time apt to the detect and control water content of raw materials after
◆节省能源。与烘箱相比，可节能30%～65%；
◆Save engery. Compared with oven, 30%～65% energy can be saved;
◆树脂料充分干燥后，以热状态落入成型机，可缩短树脂熔化时间，增加射出速率；
◆After fully dried, the resin materials drop to molding machine in hot state, which can shorten the melting time of resin and increase the injection rate;
◆不锈钢、铝合金制造，保持原料清洁。
◆ Stainless steel and aluminum alloy are used for manufacturing. Keep raw materials clean.

SDG系列干燥机的选用方法：
Selection methods for SDG Series dryer:
按配套成型机规格大小选择干燥机极为重要，选择规格过大，浪费能源，浪费资金，反之则干燥效果不良，为达到高效率干燥效果，保证物料充分干燥，一般可根据成型机每小时射出量计算，其选择的干燥机装料量应略大于下列计算值：
It is extremely important to choose the dryers according to the specifications and size of supporting molding machines. It the selected specification is too large, the energy and funds will be wasted, otherwise the drying effect will be undesirable. In order to achieve highly efficient drying effect and ensure to keep materials fully dry, generally calculation can be in accordance with the injection amount of molding machine per hour, and the loading volume of the selected dryer should be be slightly larger than the following calculated value:
◆ 干燥机装料量=成型机每小时射出量X原料干燥时间
◆ Dryer Loading Volume = Injection Volume of Molding Machine Per Hour × Drying Time of Raw Material
◆ 各种塑料颗料原料干燥时间见附表一，如实际使用中原料经常变换，干燥机装料量=成型机每小时射出量X2.5h。
◆ Drying time of various kinds of plastic granular raw materials refers to Attached Table 1. If raw materials are often changed in actual use, then dryer loading volume = Injection Volume of Molding Machine Per Hour × 2.5.
