Design of a Food Conveyor and Virus Disinfection Machine

,


Introduction
Taking care of people's health is important to achieve a healthy life free of diseases.Today in the world, there are more than 300 diseases that are caused by the ingestion of damaged food, from production to marketing.Spoiled food can present simple damage from diarrhea to the point of cancer [1].
Poor food disinfection and contamination in markets or food marketing centres leads to monetary losses and also to the loss of life.In addition, according to a WHO figure, every year, unhealthy food-borne diseases cause the deaths of 125,000 children under 5 years of age [2].
People all over the world are at risk of contaminating or having their food contaminated when preparing a dish for consumption.This can occur in the places we visit most, whether in a restaurant, in our home kitchen, or in some work or study institutions.The most common cases are, for example: if a worker in charge of food handling is ill while performing his work, if kitchen utensils are used for all types of cutting such as chicken * Corresponding author : 75142200@continental.edu.pe† Corresponding author : 74141494@continental.edu.pe‡ Corresponding author : 76375240@continental.edu.pe§ Corresponding author : 73141231@continental.edu.pe** Corresponding author : 71014985@continental.edu.pe† † Corresponding author : mberaun@continental.edu.pe and later vegetables, and it can even occur in the refrigerator, when meat juice is in contact with products that are consumed raw [3].
In previous studies, a disinfection system for chemical products was proposed, but difficulties such as respiration, skin irritation, and others were encountered.Likewise, there are mechanical disinfection systems where the process is based on product control, either at the time of packaging or processing [4].
Based on this, we propose the design of a machine for food transportation and disinfection with UV rays for proper handling throughout the food production chain.It is a machine with several utilities focused on the elimination of microbes, which multiply rapidly when exposed to ambient temperature.Reheating or boiling food after it has been at room temperature for a long time does not always make it safe because some microbes produce toxins that are not destroyed by heat.Another utility of the machine would be to take the temperature to verify the state of the food and if its temperature is adequate for its conservation.

Materials and Methods
We used the VDI 2221 standard created by the "Association of German Engineers'' (Verein Deutscher Ingenieure, VDI).This standard allows us and gives us more facility to change and vary the design and functions of the machine [5].
Which starts by finding a solution to a problem or need, among the most important steps is the construction of a morphological matrix that finds all the functions that are needed to fulfil the desire, and then the mechanism for each task is implemented for electronic design, remote control, and mechanical design to obtain an optimal solution, as shown in Fig. 1.

Morphological Matrix
Several matrix-based tools and techniques have been developed.A matrix is typically used to track and visualize relationships between product features and/or design process features [6].The authoring tool is a detailed description of a generic morphological matrix basket, where each feature is presented in a separate table showing the sub-function and data source [6].
Similarly, the morphological matrix is derived from the concept of the non-dimensional morphological box (Zeiler and Wilson, 1967).The two-dimensional form of the "Zwicky Box" is called a "morphology diagram" and consists of carefully defining and delimiting all important elements of the design and listing possible solutions for each feature [7].
Morphology is also a concept introduced by the physicist Zviki.One of the ideas of morphology is to systematically search for solutions to problems that can be combined in matrices.This search to discover even unusual combinations is one of the basic components of creativity, similar to inventive problem-solving theory [8].
Therefore, a morphological matrix of components was proposed for possible solutions in the design of a food conveyor and virus disinfection machine, as shown in Fig. 2.

Black box
Several circuit breaker black box models have been proposed since Cassie's pioneering work in 1943.However, there are two main reasons why "another" black box model is needed today.An accurate tool to simulate the complex physics it describes.The opencircuit phenomenon of a circuit breaker is CPU intensive, so the available black box models have been tried.The physical complexity of circuit breakers is reduced to a few simple equations, but they are inaccurate and do not fit perfect operating conditions [9].The general functions of the food conveyor and virus disinfection machine can be represented by a black box, which is presented in Fig. 3. • Unloading: They will mainly serve to enable the sick person to take their respective food from the food tray.• Battery: Place that will power the entire machine operation.• Tablet and speaker: In this area they will receive information about the temperature and also about the food, by this means a communication can be made between a doctor and the hospitalized person.

Job description
As can be seen in the following Fig. 4, the electronic design for the 0N/OFF power-on operation is shown, which will also ensure the safety of the health professionals.
Likewise, the electronic design was carried out in the "Proteus" software, because of the libraries and components necessary to carry out the simulation correctly.

Remote control
Modern robotic system implementations are increasingly related to autonomous robots.However, especially when a mobile agent is operating in an unknown and dynamic environment, it may face situations where its control system cannot find a suitable solution to solve the problem, leading to a deadlock and abandonment of the mission.A possible solution to this situation is the implementation of virtual teleportation (VT) technology [10].
The online programme "AppInventor" was used for remote programming of the machine.Its programming is shown in the following Fig. 5.

Design mechanic
The application object is the top level of the AutoCAD object model and the root of all other objects [11].Almost all drawing elements that can be created and edited using the AutoCAD GUI have equivalent objects with properties and methods associated with the AutoCAD object model [12].To observe and measure the machine, it is estimated to weigh about 10 KG, as seen in Fig. 6.The selection of the materials to be used in the mechanical design and electronic design for the food conveyor and virus disinfection machine was carried out as shown in TABLE I.

Results
This section presents the results obtained from the food conveyor and virus disinfection machine, making use of the free software "App inventor", for the programming of the remote control and also making use of the software to simulate the operation of the electronic design.Therefore, a fully functional electronic circuit was obtained, as you can see in Fig. 8 and Fig. 9, below.This circuit serves to activate the fluorescent lights and also shows the time of 20 seconds in which the lights will turn on, so that the person who activates the lights has the necessary time to leave the place.Once the sensor detects this, it starts counting, continues for only 20 seconds, and activates the UV lights.The control of the processes carried out in the food machine, as shown in Fig. 11, is a result of performing the programming in the free software Appinventor," which has action buttons and a remote control.Finnally, a graph of the approximate price and the ideal solution for the proposed prototype was obtained, as shown in Fig. 12.

Conclusion
We can conclude that this machine is important to be able to combat the various diseases generated by microorganisms, as it has many functions that are very useful for the disinfection of viruses and bacteria, as it eliminates 99% of those mentioned.This machine will help monitor food remotely at any time and will have the appropriate equipment to control the microorganisms that exist in food.With the proposed design, we realized that its application could be used in hospitals and/or clinics, as well as in hotels, where it could play a very important role in the disinfection of guests' food, thus offering a much cleaner and more reliable service to customers.in the future because of the difference between brain structure and neurobehavioral between male and female, (2) More realistic cognitive task such as officer jobdesc, editing text, and more realistic cognitive task can be used in the future, (3) EEG measurements can be added with other physiological factors such as skin temperature to further eliminate the effect of room temperature and improve the assessment.

Fig 11.App OF remote control TABLE II shows the technical and economic valuations of the concepts of the proposed project based on the morphological matrix.It was possible to obtain a technical and economic valuation that is equivalent to saying that it is more reliable and cheaper; for this reason, the VDI 2225 is endorsed, which indicates a cost methodology in a precise manner.

score 0 to 4 (Value scale according to VDI 2225) 0 = Not satisfactory, 1 = Fairly acceptable, 2 = Adequate, 3=good, 4 = very good Evaluation criteria for design at concept or project stage.
Therefore, to calculate the approximate economic value of the project solution, an allowable manufacturing cost was obtained, which was multiplied by 0.7 to obtain an ideal cost, which was used to find the economic value, since this is equal to the ideal cost divided by the approximate price and the allowable manufacturing cost, as shown in TABLE III and TABLE IV.
