Juicer for citrus fruits

 

(57) Abstract:

Juicer for citrus fruit intended for use directly in bars and restaurants for squeezing citrus juice and includes two rotating towards each other roller, the periphery of which is made according to three hemispherical depressions corresponding to the size of the fetus. Between the rollers is set knife. Each punch is made in the form of a truncated ball, an eccentric fixed to the output shaft. Its final drive ratio of the kinematic chain roller and punch chosen so that for one revolution of the roller punch makes so many full turns, how many hollows has roller. Feeder fruits made in the form of a disk rigidly mounted on the output shaft of the drive inside the shell with a gap. This embodiment of the juicer allows you to significantly reduce its overall dimensions, which is particularly important when it is used in places with limited space. 1 C.p. f-crystals, 3 ill.

The invention relates to automatic machines for the preparation of freshly squeezed citrus juice in terms of bar, restaurant, external trade, etc.

Known devices intended for the same purpose, naprelan on the capture of the fetus, cut it half in two rotational movement of the gripping bodies 180oand subsequent squeezing the pulp of the fruit of the translational movement of each of the halves meet two stationary mounted punches.

The disadvantage of this device is increased dimensions, due to the need for accommodation complex mechanism that provides a first rotational, and then the translational movement of the gripper bodies.

Other devices of similar purpose is a machine for extracting juice from fruits (U.S. patent N 5655441) providing uniform compression of the fetus with all parties during translational movement of the punch having a concave hemispherical shape, formed lastcoupondate plates within the space between the same plates of the matrix (remove juice is made through the cutter tube form).

The disadvantage of this device are increased dimensions, associated with the need to accommodate drive high-power, sufficient to compress not only the pulp and peel. The increase in size here due to the need of converting rotary motion into reciprocating through the crank-stopredeye the ratio of the volume of pressing and the clearance between the punch and the matrix.

The last disadvantage is eliminated in the juicer equipped with a mechanism for cutting the fruit into halves and mechanism of extraction of juice made in the form of two synchronously rotating drums, one of which is performing the role of a punch inserted eccentrically inside another, larger in diameter and the role of the matrix (U.S. patent N 5628247). However, because this device deforming surface in the form of a cylinder, the inevitable breaks the peel of the fruit, the hit of bitter oils and acids contained in the peel into the drink, and as a consequence of the deterioration of its quality.

The higher the quality of the drink and reduce energy costs provide a device with rotating towards each other matrices, made in the form of hemispherical depressions in the two rollers (U.S. patent N 2270007, 2707981); punches made in the form of Polukarov using a system of gears associated with the rollers. During the rotation of the rollers citrus sink into the hemispherical cavity, cut in half and the juice from the pulp is extruded hemispherical punch. This method provides good quality drink and completeness of the extraction of juice even when the variance of the size and shape of the fruit.

the attraction of juice, characterized by a more rational choice of the number of depressions in the roller - three depressions in every movie that minimizes the dimensions of the system matrices (U.S. patent N 5313879). This is confirmed by the prevalence of machines built according to this scheme on the modern market (for example, juice machines company Zumex).

For reasons that impede the achievement of specified following technical result when using the closest analogue, should be attributed to the increased size of the device, which is caused by the necessity to provide a large space to accommodate the system of punches - two block punches three Polukarov element in each. Large block sizes of punches also lead to the need to ensure high torque, as these dimensions define the shoulder when calculating the required torque, and hence the size of each element of the transmission - couplings, shafts, bearings and so on.

The objective of the invention is to reduce the dimensions of the extractor, which is a decisive factor in the choice of a particular machine as it is installed directly in the limited service area of the bar filled with other kinds of the opportunity calibration fruits, therefore, the machine should be able to press and very large fruit - at the same time, the size of the fetus determines the minimum possible dimensions of the machine that creates the technical contradiction - compact machine for bar should be able to overcome larger fruit than even industrial installation for which it is possible to arrange the calibration and to allocate a special operator.

To address this main tasks and aims of this invention. The smaller machine can receive a range of additional benefits - weight loss, material use, energy consumption, production costs, transportation, customs duties and taxes, the cost of insurance. In addition, it facilitates the design of the product created on the basis of the present invention, which is very important for use in bars.

This is achieved by the fact that each punch is made in the form of a truncated ball, an eccentric fixed to the output shaft, and the gear ratio of the kinematic chain roller and punch chosen so that for one revolution of the roller punch makes so many full turns, how many hollows has roller. It also promotes vozmojni shell with a backlash.

In Fig. 1 shows a juicer, front view; Fig. 2 - the same, the cross section of the side view of Fig. 3 - section a-a in Fig. 2.

Juicer for citrus fruit consists of a casing 1 in which is located the drive motor 2 which is connected with gear 3, the output shaft of which is connected with the shaft 4. On the last rigidly fixed gear 5 which engages successively with a system of series-connected gear wheels 6, 7, 8, each of which is located on its own shaft 9, 10, 11, respectively. Gears 6, 7 are in this case three times more teeth than the sprocket 5, 8.

On the shafts 8, 5 rigidly fixed two punch 9, 10, each of which has the shape of a truncated ball. On the shafts 7, 6 fortified two rollers 11, 12, the periphery of which is made according to three hemispherical recesses corresponding to the size of the fetus. Between the rollers is set knife 13. Rollers and plungers are enclosed in a casing 14, in the lower part of which is placed a filter 15 and the tray 16. Under the hood is a waste box 17. At the top of the juicer is the feeder of the fruit, consisting of a plate 18 rigidly mounted on the shaft of the actuator 19, and the shell 20.

The device of robotson 10 clockwise, resulting in a rotation of the whole system of gears 5, 6, 7, 8. As a result, the rollers 11, 12 are rotated inside, grab the fruit and cut it on the knife 13 into two halves, and upon further rotation of the plungers 9, 10 squeeze the juice from the fruit and rind of waste sticks to punches and thrown in a box 17 waste. Simultaneously with the turning on of the motor is the actuator 19 of the drawer, the disc 18 rotates and produces feed to the rollers 11, 12 of the next fruit. After submitting the required number of fruits (usually requires three oranges to fill a 200 ml Cup) motor 2 and the actuator 19 are disconnected control device (not shown), and the process stops until the next power-on.

The invention allows to significantly reduce the width of the extractor in comparison with the best.

1. Juicer for citrus fruit, composed of feeder, fruit, two kinematically interconnected shafts are fixedly mounted two gripping roller with hemispherical depressions corresponding to the outer surface, mechanism for cutting the fruit into pieces, consisting of a knife fixedly mounted between the gripping rollers, and mechanism vidablue and kinematically connected with the gripping rollers, characterized in that each punch is made in the form of a truncated ball, an eccentric fixed on the output shaft, and the gear ratio of the kinematic chain roller and punch chosen so that for one revolution of the roller punch makes so many full turns, how many cavities have the movie.

2. Juicer under item 1, characterized in that the device for feeding the fruit is made in the form of a disk rigidly mounted on the output shaft of the drive inside the shell with a gap.
