• the invention relates in particular to a vending machine for fried products that has a freezer cabinet with a frozen product dispenser that drives the product to be fried to an electronic scale, which weighs the received product, transporting it in a loading cart located in the inside of the freezer from the balance to the fryer.
• vending machines of all kinds are known, and among them are the vending machines for food products, and more specifically for potato chips, in which, after payment by the user, a dosage is made, Preparation and delivery of the fried product.
• the Spanish invention patent with publication number ES2107367 describes a vending machine that improves the previously existing ones, presenting a fryer with a smoke scrubbing system that has a blanket and activated carbon filter system, whereby it is improved the filtration of the frying fumes.
• the outgoing smoke from the fryer still had a large amount of contaminating particles that were not removed by the filters, and a high moisture content.
• this vending machine had dosing means comprising a conventional blind helix auger that drags the products, which presented the disadvantage that sometimes, and especially when the initial products had different sizes, the auger got stuck. It also featured a freight car and a dosing scale to prepare the dose of product to be fried.
• the present invention solves the problems existing in the state of the art by means of a vending machine of fried products with a freezer cabinet, for the storage of the product to be fried.
• the product to be fried can be any of the products marketed by the different manufacturers of frozen pre-cooked products, and is introduced in bulk into a hopper inside the freezer cabinet.
• the freezer cabinet additionally has a product dispenser that feeds an electronic balance to weigh the product to be fried, and this product to be fried is supplied to a vertical fryer through a mobile loading cart driven by a gearmotor and located inside of the freezer.
• the vending machine object of the invention has dispensing means of accessories such as sauces, sai, cutlery and napkins, which together with the fried product is delivered to the customer in a package provided by a dispensing mechanism. All operations performed are managed by an electronic control system that governs the vending machine.
• the user makes the payment in the machine and chooses a type of frying and some complements, and the fryer fry the product that he has received directly from the storage hopper, located inside the freezer cabinet, through the loading cart , which has been dosed by means of the electronic balance.
• the vending machine delivers it to the user in a tub along with the supplements, which are dispensed into a packet.
• the dispenser of the hopper in the freezer cabinet that deposits the product to be fried in the balance is an auger formed by a spindle that has a plurality of pivots around it arranged in a helical arrangement. The movement of the spindle is achieved through a gearmotor.
• the electronic balance is formed by a tray that has a strain gauge connected to the electronic control system, which allows to obtain an exact weight, and therefore a correct dosage of the product to be fried.
• the mobile cargo carriage As for the mobile cargo carriage, it travels through a travel spindle that is connected to a gearmotor.
• This load carriage is triple positionable along its spindle travel, from the balance to the fryer, by means of an electronic position controller arranged in the gearmotor.
• the three positions in which the load carriage can be positioned and which are controlled at all times by the electronic controller are: a first loading position on top of the balance, a second unloading position on the fryer, and a third position of Waiting for the car between operation and operation in which it is arranged between the other two positions.
• the freezer cabinet and the fryer In this third waiting position of the freight car, the freezer cabinet and the fryer are kept closed and without communication, to avoid both thermal leaks of! freezer, such as leaking frying fumes in the fryer.
• the mobile cargo car is located inside the freezer and receives from the control system the order to move to the first loading position just when a portion is being fried.
• two important advantages are achieved: first, there is one minute, which is the usual frying time, for weighing, which guarantees an absolute uniformity in the weight of all rations; Secondly, the reception time of the fried ration is shortened considerably by the customer after making their purchase, because their ration has already been weighed previously and is moved to the fryer immediately after making the purchase.
• the vending machine has a smoke purification system that is connected to the fryer. This smoke purification system comprises at least one condenser and a set of filters at the outlet of the latter. Subsequently it has an activated carbon filter, in which an adsorption filtration is carried out by means of porous carbon. Finally, the resulting filtered current is mixed with a current emitted by an ozone generator before being expelled abroad.
• this fryer is divided into two separable and connectable parts, which are: a motor and a frying chamber.

In this way, when it is necessary to carry out the cleaning of the machine's oil, it will only be necessary to remove said frying chamber, which will facilitate its cleaning, being able to be cleaned manually or in an industrial dishwasher, leaving the motor inside the vending machine .
• the fryer additionally has an oil level control system that has a series of temperature measuring probes arranged at different heights in the tank.
• the level control system has a reference temperature probe arranged at the bottom of the tank that measures the temperature in this area, and at least one other level temperature probe disposed at a certain height that measures the temperature at that height. . If the temperature difference between the reference probe and the other probe is greater than a predetermined n value, this will indicate that at that given height there is a very low temperature compared to the bottom of the tank because in that area at that given height there's no oil.
• a maximum level and a minimum level can be determined between which to place the oil level, and if said oil level is not between these minimum and maximum levels, the oil level control system disconnects the fry pan to avoid a frying with an amount of oil, either insufficient or excessive.
• temperature probes also function as an anti-fire system, since they provide instant oil temperature information. If a predetermined safety temperature is exceeded, the power is cut off automatically, the resistance that heats the oil being disconnected. Additionally, the lower oil level control will indicate when the oil level is below the active zone of the fryer's resistance, and thus prevent a fire from being caused. As an additional safety measure, there is a thermostat that would cut off the power automatically if a certain temperature was reached in a certain predetermined area, also, if a fault occurred in any of the temperature probes, the electric current would be cut off automatically.
• the vending machine fryer may also include a polar component control probe, and the fryer will automatically disconnect when the values measured by the polar component control probe are outside a preset range and since the oil could be harmful to health.
• the machine has a pump that is connected to the fryer, and with this, and with the help of a filter that is arranged inside the fryer, a filtering of the fryer oil is performed when the measured values by the controlling probe of polar components are outside the preset range, that is, when the quality of the oil does not meet minimum legal conditions.
