Description

Process for controlling squeezing juice from organic products

The present invention relates to control with the squeezer of a mill room that is provided with the band drain means and drivable pressing device method to squeezing juice from organic products.

For this purpose, main adopt machinery, air pressure or hydraulic operated squeezer, and pressing device mainly is designed to piston or flexible membrane.Whole expressing process is finished through repeatedly squeezing continuously circulation.

In the single pressing circulation, pressing device is pressed to the pastel that appears in the mill room at first constantly, is drawn back to resting position again subsequently.In drawback movement, the pastel of the fruit of fruit, grape or its class is for example done pine by the squeezing container rotation regular hour.In this squeezing mode, the duration of each squeezing circulation is pre-determined, and the variation with parameter in the expressing process does not change.

When adopting the mode of production of this intermittent type,, has decisive significance for the economic benefit of a squeezer to a certain amount of required time loss of pastel of waiting to squeeze the juice.

This is interpreted as obtains a high fruit juice output and has avoided the fruit juice that obtains is produced injurious effects in as far as possible short total squeezing cycle.

The task that the requirement of this versatility faces the present invention has proposed high requirement.

It thus professional people's bodyguard proposed following task, promptly provide a kind of control to organically, mainly being the method that the fruit of agricultural product such as fruit, vegetables, grape or its class is squeezed the juice with a squeezer, adopt this method, in by short total squeezing cycle, obtain high fruit juice output and do not cause mass loss and obtain high economic benefit.

Realization, conserve energy consumption that relevant ideal squeezes the juice process should be provided simultaneously, reduce the guidance of loss aspect.

Solves by following approach by this task of the present invention, i.e. the squeezing stroke that a squeezing circulates will finish when maximum is squeezed the juice capacity reaching to obtain in this squeezing circulates the earliest.

Squeezing circulation is when the squeezing stroke of a last squeezing circulation interrupts, and it comprises the squeezing stroke that the backhaul of pressing device, possible loose stage and this squeezing circulate.

When adopting method of the present invention, after the press charging, the first squeezing circulation beginning, when it had just reached maximum and on average squeezes the juice capacity, then this squeezing stroke had begun the process by the inventive method with regard to end.

The time of a squeezing circulation continuous is depended on the maximum of two the squeezings circulations in succession capacity of on average squeezing the juice, and simultaneously, the on average capacity of squeezing the juice that obtains in the circulation timei that consumes is equivalent to mean value.

Finish at the squeezing stroke, pressing device begins after the backhaul, next squeezing circulation beginning.

The maximum of a squeezing circulation on average squeeze the juice capacity LQ by in a preset time, the fruit juice capacity Q that obtains of each chronomere calculates, it sharply rises when beginning at the squeezing stroke, and the decline that can squeeze degree owing to the material of squeezing the juice subsequently reaches the maximum of the capacity of squeezing the juice.Reach the optimum economic benefit of each squeezing circulation at this critical localisation.

Test proves, can further improve the economic benefit of a plurality of squeezings circulations when agricultural product are squeezed the juice by following method, namely just reach maximum that this squeezing obtaining in the circulating capacity LQ(Ko that on average squeezes the juice when the squeezing stroke of a squeezing circulation ... Kx) finish after.After this general restriction is considered with squeezing circulation, by experience, its maximum is the capacity of the squeezing the juice maximum that will the be lower than front squeezing circulation capacity of on average squeezing the juice on average, and for the cause of the economic benefit that is conducive to this method, the capacity of the squeezing the juice difference in two squeezing cycles will be dwindled.

If the squeezing stroke of a squeezing circulation is not maximum of expection in reaching next squeezing circulation the capacity LQ(Kv that on average squeezes the juice) finish the back, then may obtain further improvement, like this, consider pastel is carefully handled.

When the instantaneous capacity Q that squeezes the juice reaches the squeezing stroke that finishes a squeezing circulation when maximum of expecting in next squeezing circulation is on average squeezed the juice capacity LQ, prove best results, so just can avoid pastel is excessively squeezed, in the hope of guaranteeing favourable economic effect.This processing mode is based on the average result that compares of the capacity of squeezing the juice of the maximum of expection in instantaneous squeeze the juice capacity and next compacting circulation, and is specially adapted to fruit, fruit, grape or other agricultural product are squeezed the juice.

Squeezer with following structure proves a kind of device that is rich in advantage, fruit juice discharger on it or fruit juice gathering-device have a measurement mechanism that is independent of the mensuration discharge fruit juice amount of squeezer, it is connected with a processor, and this processor is connected with the device of a control squeezer driving mechanism.

According to method of the present invention, can improve the economic benefit of a plurality of squeezings circulation that agricultural product are squeezed the juice, the total maximum that in the shortest possible total squeezing cycle, the obtains expection capacity of on average squeezing the juice.

Other details of the present invention and advantage can be from behind explanation and accompanying drawing in find out, allly relate to not elsewhere specified details herein, can consult accompanying drawing.

Fig. 1 is the curve table diagrammatic sketch of method of the present invention,

Fig. 2 is the curve table diagrammatic sketch of the improved embodiment of method of the present invention,

Fig. 3 is a schematic diagram of realizing a flow measurement device of method of the present invention.

The method that Fig. 1 represents with curve illustrates the process of the method controlled of squeezing the juice that organic products is mainly referred to the agricultural product of fruit, fruit, grape or its class with a squeezer by quantity (Q) to the curve of time (T).In the first squeezing circulation in time T o, pressing device moves to pastel from resting position, and before the maximum that reaches this squeezing circulation was on average squeezed the juice capacity LQ, it was keeping the squeezing state always.Originally the output of squeezing the juice increase sharply, subsequently gradually mild, and this moment, the fruit juice amount was on the increase, simultaneously on the other hand, the capacity of on average squeezing the juice, the average fruit metering that also namely reaches in the moment of setting reduces after it reaches its maximum gradually.Except these parameters, the curve of the instantaneous capacity Q that squeezes the juice skyrockets when beginning, and descends to be similar to the same gradient and asymptote ground after reaching heap(ed) capacity.Be the turning point on the capacity curve of on average squeezing the juice below the Q high, after this, the on average capacity of squeezing the juice of rising changes the line segment milder than peak dot into, falls again then.Peak dot simultaneously is again the crosspoint of capacity LQ and the instantaneous capacity Q that squeezes the juice of on average squeezing the juice, and its available flowmeter and calculator are determined.Leave this moment, expressing process should finish, next squeezing circulation beginning.Next squeezing circulation begins to draw back pressing device, illustrates in the time interval T in Fig. 1.When drawing back pressing device, also can be for example by rotating the squeezing container pastel that loosens.In Fig. 1, draw back pressing device and represent with symbol T, loose (pastel) represents with T.The duration of each squeezing circulation is depended on the process of employing method, and it changes.Squeezing circulates the more, and the instantaneous capacity of squeezing the juice is lower.

Shown in Figure 2 compares with the mode of carrying out of Fig. 1 by procedure of the present invention, and the beginning of squeezing circulation postponed, and the backhaul that is to say pressing device is carried out later on reaching the maximum capacity of on average squeezing the juice.This measure is based on following truth, and namely in expressing process, the capacity of squeezing the juice of each squeezing circulation is reducing.For fear of the rapid decline of the capacity of squeezing the juice that undermines expressing process efficient, can be by closing or draw back pressing device later on and reach the capacity of on average squeezing the juice that causes next squeezing circulation reaching maximum, thereby this mode of carrying out must be based on empirical value.It should be noted that because temporal delays Kv this moment, the expection maximum that next squeezing circulates on average squeeze the juice capability value can not be more down.Have only when momentary output Q and the expection maximum of next squeezing circulation and on average squeeze the juice capacity when consistent, the squeezing stroke that squeezing circulates just may finish.

The squeezer of a known type can be used as the device of realizing the inventive method, has connected a flowmeter as the processor transmitter at its row's juice device, and it can control the drive unit of the squeezer that adapts with existence conditions.

Press Fig. 3, receiving slit 3 or similar containers on a kind of tapping equipment 2 that is connected pressing device, that have the wall 4 that is designed to overflow mechanism are suitable for as flowmeter.Be provided with one as the pressure tester 6 of measuring transmitter at the measurement pipeline 5 from bottom importing receiving slit 3, it measures the level variation that produces in each squeezing circulation, and sends processor 7 to.Certainly, float, ultrasonic wave or be contained in the level that the manometer of receiving slit bottom also can be used to measure in the receiving slit and change.According to the value of noting by a processor, the drive unit of control device 8 control squeezers 9.When each squeezing circulation finished, receiving slit 3 was drained by a discrete pipeline 10, for this reason, was provided with one with processor or hand-operated slide unit 11.Receiving slit 3 self has been installed the bottom 11 that upwards resets, thereby fruit juice can be flow in the scope of measuring channel 5.
