Full automatic line JetNut 744 (nut)

Our production facilities are located in Bulgaria (Varna) – European Union.

Full automatic line “JetNut” for the production of cookies “Nuts” with various fillings. Produced since 2021. We managed to automatically connect two cars that were previously sold separately from each other. We have designed and manufactured an automatic manipulator that transfers nutshells from the Jetnut 744 oven where they are baked to the Nutfiller automatic nut shell assembly machine. Thus, a fully automatic line for the production of biscuits “Nuts” became a reality. Two people can work on the line: the operator of the Jetnut 744 furnace and the operator-controller of the Nutfiller machine. One person should be constantly involved in preparing the dough and filling the dough hopper on the Jetnut 744 oven.

Bakery oven for industrial baking test biscuits “NUT” (tartlets, modification) JetNut 744 sample 2022 model line.

The JetNut 744 is a specialized (not universal) unit designed to produce the highest quality product, in this case, the “Nut” shell with the lowest possible costs, both in terms of electricity and human resources. The dough pump is designed specifically for work with a traditional thick sand dough. These conditions limit the versatility of the stove. Although the machine can be equipped with any shape, versatility is limited to a specialized dough pump for each product. The principle of “one machine – one product” gives the lowest possible cost and excellent quality.

The principle of the furnace is based on the simulation of hand-baking cookies by hand semiautomatic devices. This approach gives the best result in the taste of the product, stable geometry, baking and energy consumption. Nevertheless, the industrial production of this biscuit presents stringent requirements for production.  One of them is to minimize the surplus dough. For this purpose, the unit is equipped with a specialized jigging machine (dough dosing machine). If the oven is properly set, there is no surplus in 95% of the cases.

The NutFiller device is made in the form of a line that stage-by-stage, as delicately as possible, with high precision and accurately carries out the process of assembling the finished Nut.

The order of operation of the device is as follows:

Operators manually place Nut Shells* on the conveyor

A step-by-step conveyor moves transport carts filled with Shells from one section of the line to another.

• The first section is the section for grading and preliminary visual control. Here the operator checks the integrity and correctness of the geometry of the Shells sent for alignment. If necessary, it rejects the damaged ones and replaces them with whole Shells. The parking time of the transport cart on the site (with 24 shells on board) is 14-16 seconds. Corresponds to the setting of the JetNut 744 furnace with which the NutFiller is synchronized.
• The second section is the section for aligning blanks before gluing. In this area, the shells on the transport trolley are aligned relative to each other using a special mechanism. Proper alignment is a guarantee of geometrically correct and accurate gluing of the Nut. The alignment time is the same – 14-16 seconds.
• The third section is the section for the final visual inspection of the Shells immediately before filling and gluing. The parking time of the cart with 24 Shells is 14-16 sec.
• The fourth section is the filling and gluing section. With the help of a special technology, two Shells are almost completely closed and the almost closed Nut is filled with a filling. This solution prevents the filling out from splashing out and prevents the filling nozzles from getting dirty.
• The fifth section is the section for impregnation and aging of the closed and stuffed Nut from the bottom side. In this area, the nut is impregnated and glued along the bottom line of the joint. The time spent on this site is from 2 to 3 minutes.
• The sixth section is the section for impregnation and holding of the upper line of the nut joint. On the approach to this section, the transport trolley with already closed 12 Nuts turns over. Thus, allowing the back (top) line of the Nut joint to be impregnated. The holding time of the Nut in this area is 3 – 3.5 minutes.
• The seventh section is the section for unloading the finished Nut. At this point, the transport trolley opens and the finished, securely fastened Nut falls onto the unloading hill, thus entering the receiving container.

The main feature of the NutFiller device is the ability to produce delicate, accurate assembly of the Nut without displacement of the Shells relative to each other, without splashes of the filling and associated contamination of mechanisms and products in contact with the Nut.
