Description

The proposed device for quantitative determination of starch in potatoes is a development of a device for determining the volume of vegetables, etc., described in the author's certificate No. 21487, and is also based on the principle of dependence of the specific weight and starch content of potatoes, as already known Reiman scales, hydrometer method, etc.

FIG. 1 is a front view of the entire device; in fig. 2-part instrument with scale; in fig. 3-part transmission to the toothed rail.

The device consists of three main parts: jk-for volume determination,. weight and -P-; scale for results.

The device .L consists of a cylindrical vessel 1, in which the water (or other liquid) is contained, the level of which is regulated by the drain valve 5. The material under study is lowered onto the grid 2, under which the elastic membrane 3 (rubberized silk) is suspended. Lattice 2 and membrane 3 are reinforced with hoops 4. Between ne; by the flap 3 and the bottom of the vessel, the space is filled with air (or another gas) n "bd by a certain pressure regulated by a valve b. Space D

connects an {{open tube 7} with an open tube 8 fixed on the scale 9. In the cranked tube 7 there is mercury in an amount strictly balancing the pressure of the liquid column in the vessel 1 per membrane 3. The device is based on the following: the body descends on the grid 2; from this, the level of the liquid column in the vessel 1 rises; elevation leads to an increased pressure on the membrane .3, which is transferred to air (gas) enclosed in space D, the air rises out, slightly raises mercury in the elbow tube 7, and the height of the mercury rises and shows on an empirically compiled scale 9 volume of the body. The device -A is fixed to the device 5 on the rod 10 entering the vessel. 12, where base 11 rests on mercury (or glycerin) poured into a communicating vessel 12 and 13; plate 14 lies on mercury (or glycerin). An unequal arm of the rocker 16 with the feet 15 and 17 is connected with the plates 14, 14, 18 and 19 as communicating vessels, with 19 more than 1c. On the mercury column (glycerin) placed in vessel 19, a liter plate 20 is carried. on itself is a curved rod 21, to which is attached a pointer 22 of;

thin celluloid plate with induced thin line 1. Box 28, installed on bandages 29, covers the lower; parts. The device strictly balances the weight of the unloaded instrument 4d under the load of the device shtgga 10, lowering, presses on the mercury (glyce, rir) in part 12 and the pressure is transferred to part 13 and lifts the plate 14 somewhat. The rod 15 presses on the balance 16; the long arm of the rocker arm 16 through the rod 17 presses on the plate 14; plate 14 transmits pressure to mercury (glycerin), in vessel 18, mercury rises from this. (Uep) in vessel J19; elevation / mercury (glycerol) in vessel 19 entails raising the rod 21. Indicator 22 on an empirically compiled scale 24 gives weight readings. The scale Γ consists of fixed 1} fins 9 and 26 and a moving average 24; on a scale of 26, divisions are obtained, obtained according to chemical analysis of starchiness for a given specific weight of potatoes. With the help of bevel gears 27 and a toothed rack 30 24, on which the weight of this material is indicated, with its indicated division (weight) is opposed to division, indicating the volume of this body on a scale of 9. Pointer; 1 25 by 26 gives the percentage of starch in the potato being eaten. The scale / is fixedly attached to the vessel 1 and the determination of weight and volume is reduced in a single position. walkie-talkie.

The subject matter of the invention.

Claims (2)
