Liquid fertilizer came into wide production and use by the customers in the end of the 20th century. The process of application of such fertilizer can be fully automated, since spraying of the liquid or adding it during planting does not require operator interference. Among the advantages of liquid fertilizer compared to dry mixes is simple storage, transportation, safety and, most importantly, low cost of production. They are also independent from the weather and moisture.
Liquid fertilizer contain, beside nitrogen and phosphorus, ammonia, urea ammonium nitrate solutions, potassium chloride. Production of liquid fertilizers can be performed at cold or hot temperature.
Naturally, production of liquid fertilizers should be organized together with production of dry fertilizer at the same facility. Combining the two production processes in one location allows to reduce raw material losses by using the share of unprocessed phosphoric acid and ammonia left over from switching the facilities from one type of fertilizer to another. This increases production capabilities and efficiency.
The range of liquid fertilizer products must comply with the demands of the agriculture. The production must meet the demand and offer quality products. Companies must always increase the technological capacity.
There is no special equipment as such in the production liquid fertilizer. The equipment used is mostly various types (vacuum, mill, vane) of mixing equipment.
GlobeCore’s USB type units, which are becoming quite popular with the manufacturers worldwide, are more and more used in basic chemical processes, being formerly employed mostly in the fuel production industry.
The USB type unit makes the process of liquid fertilizer production more efficient due to high rate of production and compensates the time required to purity the liquids from contaminants.
If the units are equipped with filters, they also reduce the amount of operations performed using other equipment.
Semi-automatic control facilitates easy process management, allowing the unit to be used without the operator according to the formulation, maintaining temperature and component portioning.
