Automatic Onion Production Line

The onion processing line has continuous automatic production, fast processing speed, high output, good quality, and a low-temperature drying method maintains the original flavor of onion powder. It includes onion peeling and head removing machine, onion washing machine, onion slicer, air dryer, onion dryer, onion grinder, onion powder packaging machine, and other equipment.

This onion processing line is divided into three parts: pretreatment part, drying part, and grinding part. The pretreatment part is dedicated to onions. The dried and ground parts can be used for other spices, such as garlic, ginger, etc. The processing line adopts advanced technology, high onion output, and direct sales at factory prices. This is the best choice for the onion business and the most ideal equipment for onion processing at present.

Onion peeling and head removing machine : Onions are very easy to scratch and will deteriorate quickly, and wearing out the peeler will increase the problem. The updated machine blows away the onion skin without making surgical incisions and cutting ends on the onion skin. Onions are not handled manually, and gentle handling significantly reduces spoilage.

Onion slicing machine: Cut the onion into even slices. The thickness of the slices should be 1.5-2mm. The onion slices processed by this high-efficiency onion slicer have standard product specifications with uniform thickness and uniform size, which has a good effect on the later drying process. This uniform onion slice can keep the time and effect of the drying process under the same conditions, so the overall drying effect will also be very high, which meets the processing standards of large-scale enterprises in the drying of onion slices.

Onion washing machine: Wash off impurities , rinse off the onion film, remove debris to prevent yellowish-brown during drying. The whole is made of stainless steel. Through the effect of water circulation, the onion skin will be removed during the initial cleaning of the onion. After the rinsing, the onion will follow the conveying system and enter the next process.

Air dryer (Dehydrator): onion slices can effectively remove water and shorten the drying time before drying after washing. The main purpose is to pre-dehydrate the onion slices before drying. Because the onion slicer uses the principle of water washing and slicing, the moisture content of the onion slices after cutting is super high, plus the water contained in the onion slices. If you don’t go through the preliminary dehydration treatment and directly send it to the drying host, it will cause serious cooking conditions, which will have a huge impact on the quality of the dried onion slices. Therefore, the onion slice dehydration processing equipment is used for preliminary analysis. Dehydration processing is very necessary.

Multi-layer belt onion slice dryer: The dryer is the key equipment, which determines the effect and quality of onion slices after processing. Using our mesh belt type onion slice dryer, with an intelligent control system, can make onion slices The drying is always maintained in a reasonable drying environment to ensure the effect of the finished product. The use of this onion slice dryer has the advantages of large processing output, high degree of automation, controllable drying effect and quality, and adjustable drying time. Flexible heat source selection: Coal, wood chips, natural gas, diesel, propane, electricity, etc.

Onion powder making machine: Grind dried onion slices to a fineness of 10-120 mesh. The onion grinder is air-cooled or water-cooled and can work continuously for a long time.

Onion powder packaging machine: Generally speaking, onion powder business requires automatic onion powder packaging equipment. The onion powder packaging machine has a PLC control system, which is intelligent and controllable, and can be quickly adjusted according to customer packaging requirements. Packaging weight and quantity are automatically adjusted.
