Pick what type ?

Different varieties of grain can choose different dryer. Such as wheat , rice -based food Food producing selectable Francis , mixed countercurrent type of dryer. Such as corn-based areas, Optional multi-level downstream temperature rapid drying machine . Such as rice -based areas, choose Hue Countercurrent , mixed reflux and other low-temperature , high retarding section dryer. Different type of grain  drying.Processes and different drying temperatures , depending on how much of the amount of grain drying , and also choose not to The same type of drying process and dryer. Such as food variety, or a small number of food scattered deposits Put should use small batches ( loop ) dryer or a small portable dryer. If goods Single species , quantity, short drying period and should use a large continuous dryers appropriate.

 

Choose what heat ?

Must be considered when selecting the dryer local energy resources to achieve rational use , lower costs The . If coal producing food , heat with coal , anthracite or coke is appropriate, its price Grid economy, but a large one-time investment of coal-fired stove . There are food producing oil and gas, Available light diesel oil, fuel oil or natural gas and propane as fuel stove , such fuels High cost, but a small one-time investment stove . Dedicated application of oil or seed dryer Gas stove is appropriate, because it 's the air temperature stable , easy to control , to ensure drying Seed germination rate .

 

In what environment ?

Due to the different variety of crops harvest season , and the temperature difference between north and south , such as drying time due to Factors must be considered drying effect and operating costs. If possible, avoid coastal areas at low temperatures Wet weather drying grain, otherwise dehydration poor, low productivity , high drying costs. Nearly half of the northern region is the drying time jobs below 0 ℃, the lower the outside temperature ,Desired unit heat consumption is relatively large, high cost. So bake below 0 ℃ jobs north Piping hot and dry wall and insulation should be added in order to reduce heat loss.

 

To what ancillary equipment ?

Confidential accomplish drying drying operations, to be equipped with some of the ancillary equipment. Continuous dryer in Grain storage segment should be set down material level ( or overflow pipe , etc. ) , the process should be set up temporary positions Mancang Material level , hoist should be automatically shut down and clogging alarm devices. There should be a motor overload Protection devices , and can realize manual and automatic chain control . Pai food agency should be able to achieve speed Or CVT . Temperature control instrumentation should be able to display various segments grain temperature air temperature and high temperature can be reported Police. To test the moisture content of grain should be equipped with rapid moisture tester .
