Definitions

  • the invention relates to a device for cleaning drinking straws with a loading station for loading the device with drinking straws, at least one rinsing station for rinsing the drinking straws with liquid, and a removal station for removing the drinking straws.
  • Drinking straws also called straws, are used to absorb liquids from liquid containers. They are cylindrical, elongated hollow bodies with a passage for liquids inside. In order to absorb the liquid from the liquid container, a negative pressure is generated at one end of the drinking straw. Due to the negative pressure, the liquid is transported through the passage inside the drinking straw.
  • Such drinking straws are used in particular in gastronomy. They can be designed as disposable drinking straws for single use. Such disposable drinking straws are made of plastic or paper, for example. A disadvantage of these disposable drinking straws is that the drinking straws have to be disposed of after they have been used once and therefore, especially in the catering industry, a large amount of waste is dispensed with on these disposable drinking straws.
  • reusable drinking straws are known. These consist, for example, of plastic, glass or metal. These reusable drinking straws can advantageously be reused several times. In the catering industry in particular, the reuse of reusable drinking straws results in a lower amount of waste. In order to reuse the drinking straws, it is necessary to use them again clean. Since the drinking straws come into contact with the user's saliva when the drinking straw is taken up in the mouth of the user, the drinking straws must be cleaned as thoroughly as possible, but preferably in a sterile manner. This cleaning can prevent the transmission of pathogens from one user to the next when the drinking straw is reused. This is particularly important in the hospitality industry, where there are a large number of users of the reused drinking straw.
  • the cleaning of the drinking straws is laborious, especially for the inner passage of the drinking straws.
  • This inner passage usually has a relatively small inner diameter and is therefore particularly difficult to clean.
  • the inner passage can also be kinked or rounded, which further complicates its cleaning.
  • contamination for example from the drink or the user's saliva, may remain in particular in the inner passage of the drinking straw.
  • milkshakes, smoothies and cocktails traces of milk, mint leaves, pieces of fruit or fruit pulp can remain on the drinking straw as contamination.
  • a simple cleaning of the drinking straws by pulling them through a basin with cleaning agent is often not sufficient.
  • drinking straws are known that can be divided into two halves along their longitudinal axis. In this way, the inner walls of the drinking straw are also easily accessible and can be cleaned. After cleaning, the straw can be reassembled for reuse.
  • the disadvantage here is that the drinking straw can have leaks at the connecting line of the two halves, which makes it difficult to use the drinking straw.
  • Another disadvantage is that the drinking straw first has to be taken apart in an additional cleaning step before cleaning. This increases the workload, especially in the catering industry, where many drinking straws have to be cleaned.
  • the U.S. 6,039,490 A describes a cleaning system for drinking straws. It consists of a flexible, tubular brush structure with a tubular cavity therein between a closed insertion end and an open end.
  • the cleaning system has a threaded pinch piston container, a number of cleaning solution dispensing ports provided along the length of the flexible tubular brush structure, and a number of multiple length bristles extending radially outward from the flexible tubular brush structure.
  • the cleaning system also has an end cap for closing one end of the drinking straw.
  • the disadvantage of cleaning drinking straws with brushes is that reliable heating and flow of cleaning agents for hygienic cleaning of the drinking straws is not guaranteed.
  • soiling can occur on the brushes or in the cleaning solution.
  • the high level of manual work involved in cleaning the drinking straws is also difficult to integrate into existing work processes, for example in catering establishments.
  • Insert baskets for cleaning drinking straws in dishwashers are known.
  • the drinking straws can be cleaned in existing dishwashers for cleaning dishes.
  • the disadvantage here is that, due to the lack of mechanical action on the inner passage of the drinking straws, contaminants can settle there.
  • food scraps or residues from dishes that are also cleaned in the dishwasher can penetrate the inner passage of the drinking straws and get stuck there. A reliable flushing of the inner passage of the drinking straws does not take place in the conventional dishwasher.
  • a device for cleaning drinking straws in which a carrier is provided which is filled with drinking straws and which is then acted upon within a housing with water which has a sufficient temperature and flushes the drinking straws inside and out.
  • the drinking straws have to be manually inserted into the carrier and removed from it again.
  • the DE 20 2019 003 700 U1 describes a drinking straw cleaning device, wherein the drinking straws can be inserted and removed from a housing through an opening.
  • the drinking straws are held in the cleaning chamber of the drinking straw cleaning device by means of individual holders.
  • the invention is based on the object of optimizing the cleaning of drinking straws.
  • the object is achieved in a device according to the preamble of claim 1 in that the device has a rotationally symmetrical conveying means for transporting the drinking straws between the individual stations.
  • the straws are conveyed by the conveyor between the individual cleaning stations, for example loading, rinsing, rinsing, drying and removal.
  • the conveying of the drinking straws from the loading station to the removal station can be done automatically by the conveyor. This significantly reduces the amount of work required to clean the drinking straws.
  • the drinking straws only have to be placed in the loading station and removed from the unloading station after successful cleaning. The steps of cleaning then take place in the individual stations, for example rinsing, rinsing and drying the drinking straws.
  • At least one drinking straw to be conveyable in at least one cleaning chamber of the conveying means, the cleaning chamber being able to be rinsed with liquid in the rinsing station.
  • One or more drinking straws can be transported within a cleaning chamber by the conveyor.
  • This cleaning chamber is preferably a elongated cavity in which the drinking straws are held with their longitudinal axis parallel to the longitudinal axis of the cleaning chamber.
  • the cleaning chamber particularly preferably only offers space for a single drinking straw. This prevents contamination or germs from being transferred from one drinking straw to another.
  • the cleaning chamber is rinsed with liquid.
  • the liquid is, for example, water, cleaning solution or a rinse aid.
  • the cleaning chamber advantageously has an elongated shape, particularly advantageously a largely cylindrical shape, with openings at the two ends. The liquid is introduced and discharged in the rinsing station through the two ends.
  • the cleaning chamber is particularly advantageously liquid-tight except for its two openings at the ends. This makes it possible to flush the cleaning chamber with liquids under high pressure.
  • the liquids can be introduced into the cleaning chamber at different temperatures. The time in which the flow through the cleaning chamber can be varied accordingly to achieve the desired cleaning state.
  • the components required for introducing the liquids into the cleaning chamber in the rinsing station can be accommodated within the housing of the device. In this way, a particularly compact design of the device can be achieved.
  • the components can alternatively be accommodated outside the housing of the device.
  • the components can particularly advantageously be accommodated in a separate housing. Particularly noisy components, such as pumps, can be noise-insulated in this housing.
  • the liquid can be connected to one end of the cleaning chamber from these components by a hose. Via a second hose, which is connected to the other end of the cleaning chamber, the liquid can after Flow through the cleaning chamber can be returned to the components of the rinsing station.
  • the components of an already existing dishwasher can be used particularly advantageously in the washing station of the device.
  • the dishwasher is connected to the device with hoses.
  • the liquids from the dishwasher can be fed into and out of the cleaning chamber or cleaning chambers of the device via the hoses. They wash around and through the drinking straws inside the cleaning chamber.
  • the dishwasher can run through the individual cleaning steps, for example pre-wash, rinse and rinse, and introduce the respective liquids, for example water, cleaning solution and rinse aid, through the hoses into the cleaning chamber.
  • the components already installed in the dishwasher for example heating, pump and control modules, can advantageously be used for cleaning the drinking straws in the device.
  • the additional acquisition costs and maintenance costs for the components of the washing station are dispensed with, since the components of a dishwasher that is already available, especially in the catering industry, can be used.
  • the noise generated by the device is reduced by moving the components to existing dishwashers.
  • One embodiment of the invention is that the cleaning chamber has an impact body at at least one of its ends.
  • Such an impact body can improve the positioning of the drinking straws along the longitudinal axis of the cleaning chamber.
  • the impact body can prevent the drinking straw from escaping through one of the ends of the cleaning chamber, in particular in the direction of the liquid flow.
  • the impact body is advantageously provided in the center of the inlet or outlet opening, for example as a pin extending between the inner walls of the cleaning chamber.
  • An impact body attached to the inlet opening of the liquid flow into the cleaning chamber can particularly advantageously lead to a turbulent flow within the cleaning chamber.
  • the impact body can be, for example, a pin which is inserted into the inlet or outlet opening of the cleaning chamber.
  • a further embodiment of the invention consists in the fact that there are several cleaning chambers, the cleaning chambers being separated from one another in a liquid-tight manner by a sealant.
  • cleaning chambers Due to the liquid-tight separation of the cleaning chambers, for example, neighboring cleaning chambers can be rinsed with different liquids without the liquids being mixed.
  • cleaning solution can flow through a cleaning chamber, while rinse aid flows through the adjacent cleaning chamber.
  • the cleaning solution and the rinse aid advantageously do not mix. Impurities that are dissolved or carried along in the cleaning solution during cleaning do not get into the rinse aid. This means that the drinking straw is not soiled by contaminated rinse aid.
  • cleaning chambers that are rinsed with a more heavily soiled liquid can be separated in a liquid-tight manner from those that are rinsed with a less heavily soiled liquid.
  • the sealing means can be rubber seals, for example.
  • a further embodiment of the invention consists in that the cleaning chamber can be flushed through in different flushing stations with liquids at different pressures in each case.
