Description

[Detailed description of the invention] name of invention A method and method for filling containers with a mixture of at least two pasty and/or liquid products. equipment Technical field The present invention provides a method for filling containers with a mixture of at least two horizontal and/or liquid products. Background of the invention relating to methods and devices The unexploded F14 was connected from a first storage tank to a drawer outlet of the first storage tank. The base va product is conveyed step by step into the entire supply conduit and is withdrawn from the second storage tank. addition of a defined proportion in relation to the drawn portion or dosage of the substrate product. The product is drawn, the added product is mixed with the base product and this product mixture is through a volumetric metering/dispensing device, the volumetric metering/dispensing device comprising an ejection nozzle and an inlet. a valve and an outlet valve, the inlet of which is connected to and connected to the overall supply conduit; The precise amount of this mixture is then passed through the nozzle into at least one volume. Relates to the method in which it is weighed before discharging into a container.

Such methods are particularly suitable for preparing jams or mixtures of yogurt with probes or flavorings. It is known in the dairy packaging industry for gelatin-type milk desserts.

In that case, the basic product is transferred to the first storage tank by the first pump feeding the main pipe. Products extracted from and added to the mixture are listed in the Special Table 11-5024: Ju (4) from a second storage tank by a second pump before being added to the main pipe just upstream of the drawn out. The outlet of the mixer is connected to a buffer pail (pant abut), and the buffer handle An overpressure is maintained above the product mixture within the minimum and maximum levels of the mixture. Supply of this buffer between &I4! A two-level prologue is provided to ensure that the product Mixtures of before being discharged in a metered amount through the nozzle of the marked dispenser into a corresponding container. For example, the scheme of public property as also disclosed in French Patent No. 2,067°983. It is conveyed under pressure to different metering chambers of the ik device.

This method of stamping ensures that the minimum level probe in the buffer handle contains the basic product and additives. 2) Start the pumps for dispensing each product and check the minimum level probe. said pumps both operating continuously during the cycle in which the buffer tank fills the buffer tank; to stop. This method of exercise has certain drawbacks. In effect, the first pump is This often spoils the basic product, especially when the basic product is yogurt. Canada In particular, the flow rate 02 of the bacteria 2 pump is related to the flow rate j101 of the first pump. When low, the ratio of flow rates 01 and 02 of the first pump and second pump is o 1 / D2 'n'I! It is easy to adjust IVcpI. Furthermore, the mixture is mixed in a mixer. After being processed, the two mixed products are partially separated in their different aF & Yoshi buffer circles. I might let go. Therefore, once the product mixture has been weighed and If the base product and additives are partially transferred from one container to the other, reaching weighing devices containing variable and inaccurate ratios of products.

In addition, this method uses a long conduit between the first storage tank and the buffer tank, and Since the volume of the tub is quite large, the method uses a considerable amount of the first mixture f: the first part of the product. 2. Allows rapid changes in the properties of the mixture without loss when changing to a mixture. stomach.

According to other proposals, the substrate product is stored in a tank circle, and the additive product is upstream of the mixer. into the supply conduit and into the metering chamber of the metering/dispensing device into the product mixture. and when the mixture exits the metering/dispensing device, each of the dispensed doses contains: #1 is identical to the product of addition introduced simultaneously into said overall feed conduit downstream of the mixer. Contains additive product parts.

Although this proposal already represents some innovation, it is not complete for several reasons.

That is, the exact total of the products to be added with the same exact amount is: Sweet products such as jams and syrups are additives, and 7t are sweet products such as jams and syrups. Problems arise when small pieces of the tube are present. In fact, the sweet product is connected to the metering piston. Rainbow flies #i occur in the gap that exists between the measuring chamber and the measuring chamber and enter the measuring chamber. Carbohydrates in added products are particularly susceptible to In the cap, it crystallizes under the action of oxygen.

The sugar crystals end up at f'11. of the measuring device. impede the movement and ultimately stop it.

Exiting the tank storing the basic product into a device for metering/dispensing said basic product. the presence of a mixer in the overall supply conduit that is Additive product injection point distribution ftfl metering/dispensing equipment and containers for storing substrate products does not allow for the manufacture of compact structures.

The aim of the invention is to overcome these drawbacks and to improve the quality of the products to be mixed and the mixing of products. Carefully transport and weigh the product and mix one side of the product. l+ to others The type mentioned at the beginning which causes Ic change without significant loss of the first mixture to the second mixture. VC is proposing a method for this.

Another object of the invention is to eliminate the risk of sugar crystallization in equipment for metering added products. and preferably also a tank for storing the substrate product and for metering/dispensing it. The volume of the entire supply conduit between the equipment for A filling method of the type described is proposed above.
