In our factory in Planá nad Lužnicí we operate a “Factory Test Facility” which allows to extend the range of laboratory tests for customers and at the same time significantly shortens the running time of these tests. It is now possible to process samples of any granulometry (from 50 microns to 50 mm) with results within five business days of receiving the sample from the customer.

Modern equipped test facility room

The testing laboratory is equipped with a fully adjustable laboratory vibration sorter, laboratory destoner and concentrator, laboratory pneumatic gravity table, impact dehullers and horizontal scourer, two dispensers for accurate and adjustable product measurement, as well as bucket elevator, electronic scales and equipment for granulometric analysis. If necessary, additional equipment can be connected to the test facility room.

The laboratory allows to determine and guarantee the qualitative and quantitative parameters for cleaning, sorting and peeling of a wide range of agricultural crops.

Our experienced engineers will design in most cases (where feasible) a functional technology line. If required by the customer, a real test of this proposed technology can be followed by a laboratory test on the supplied sample from the customer. A protocol is then drawn from this test.

The most demanded solutions are for cleaning, sorting and peeling cereals, oilseeds and legumes, including exotic crops. The proposed technologies, besides agricultural operations, are mainly used in food processing plants and feed compound plants.

Utilization of test room for post-harvest line

For customers who are considering, for example, acquiring a new post-harvest line or refurbishing the existing one, analyzes can be performed on the supplied sample of harvested crops at JK Machinery test facility room, which is very useful for their decision-making. Customers will receive relatively accurate information on what technology and to what extent should they buy to meet the set parameters and at the same time be economically designed.

The supplied samples are analyzed for quality parameters and bulk density, prior to cleaning and as well after cleaning on a properly set machine. Precisely is also specified the amount and nature of impurities in the supplied sample. The test is carried out in such a way that the customer obtains the most accurate view of the performance parameters of cleaning and the final quality of the commodity. An important aspect is the amount of usable and unusable waste from cleaning. Again, emphasis is placed on compliance with the individual requirements and needs of the post-harvest line operator.

The test facility room is also useful for existing JK Machinery customers. Due to the varying size of the harvested grain, depending on, for example, the hardly predictable climatic conditions, it is recommended to check the size of the cleaning sieve in that year. By laboratory analysis of the supplied sample can be quickly and precisely determined optimal sieves to avoid unnecessary economic losses due to excessive leakage of good material to the waste or failure to achieve the required cleaning quality. The manufacturer is ready for this situation and the missing sieves are delivered to customers, also in the high season, usually within two to three days.

Laboratory analysis for peeling lines

A frequent requirement of JK Machinery customers is the peeling of various agricultural crops. In the long term, we find connection with the supported trend of processing own agricultural production. The increasingly uncertainty of feed manufacturers regarding the future use of genetically modified crops, especially soybean, in compound feed processing is a growing reason for the acquisition of a new peeling technology. But new solutions exist. In addition to expanding the sowing areas of genetically untreated soybean, there is a growing trend towards replacing it with crops such as rape or lupine, where is after peeling separated the peel and part of the fiber by precision sorting. This results a protein concentration in the peeled product. If the subsequent step is pressing on mechanical presses or production of vegetable oils, then the proportion of protein in the oilseed-cake is the same as that of soy.

Precise information is necessary to decide whether it pays to invest in peeling technology. A laboratory test on a sample accurately determines what yield and final product quality can be achieved in peeling and subsequent cleaning. The laboratory test result is converted into a technology design with performance and parameters tailored to the customer’s needs. The advantage of the laboratory test is also the creation of a real sample of the final product, which the future owner of the line can evaluate in his laboratory or at his customers.
