    Different types of drying equipment have different characteristics and operating processes. Steam and hot water drying are easy to control quality, have low drying costs, and are widely applicable, followed by hot air drying. Vacuum equipment has good drying quality, fast speed, and high drying cost. Most redwood furniture production enterprises are suitable for choosing drying kilns with a single kiln loading capacity of no more than 20m3. Choosing professional drying equipment should be combined with the drying method. For example, if the enterprise has industrial boiler gas supply and steam heating drying kiln, then choose hot water heating drying kiln. If the enterprise has less funds and low output, furnace gas heating drying kiln can be selected. If the enterprise has strong financial strength and high product profit margin, vacuum drying equipment can be chosen.
