Page 3: General Information
1 General information Ekomilk Spectra is designed for fast and cost effective control of milk quality - de- tecting adulterants (ammonium sulfate, urea, etc.) and milk parameters (Fat, Solids Not Fat, etc.). The mid-infrared spectral module allows for detection of adulterants and their concentration without the use of chemicals and the well established ultrasonic module measured the milk parameters. - Page 4 Environmental conditions: Ambient air temperature 15 °C 35 °C Milk temperature 5 °C 35 °C Relative humidity 30 % 80 % Parameters: Measuring ranges: Limit of detection: 0,5 % 12 % 0,1% (abs.) Solids non fat (SNF) 0,2% (abs.) Milk density (CLR) 1,0200 1,0400 g/cm3 0,0005 g/cm3 (abs.)

Page 8: Cleaning Procedure
The order of cleaning is not important. 6.1 Infrared module cleaning Ekomilk Spectra cleaning procedure works on a reversal principle to prevent problems with cuvette clogging. NOTE: Instructions for preparing EkoZero solution are on the packaging label of the concentrate, also described in the section 4. - Page 9 Figure 3: Clean IR Full infrared cleaning The IR module requires additional cleaning. It is recommended to be performed every 14 days, if necessary more often. It is also used in cases when the device will not be used for a long time (more than a week). For this purpose is use EkoClean (it is delivered in the form of granules in 2 packages 18 grams each).

Page 10: Ultrasonic Module Cleaning
6.2 Ultrasonic module cleaning Cleaning the ultrasonic module requires more time than cleaning the infrared module because different solutions are used to maintain the ultrasonic sensor in good condition. The cleaning of the ultrasonic module is similar to the cleaning of the infrared module: •... - Page 11 Methods for daily and periodic clean of the Ekomilk Spectra analyzer’s ultrasonic module 1. DAILY CLEANING Daily cleaning is required when: • The interval between two consecutive measurements is more than half of one hour. • The daily job is finished.

Page 13: Zero Procedure
Figure 7: Hand-cleaning 7 Zero procedure The ”zero procedure” must be performed at the beginning of the working day and on every hour during the day. This procedure is necessary to account for imperceptible changes in the environmental conditions of the measurements and their compensation. Failure to set to zero may adversely affect measurement accuracy. -

Figure 12: Main menu A new window pops up asking for the measurement configuration (Figure 13). The main thing here is to select what modules of the hybrid analyzer to be used for the measurement process. - Page 17 Figure 14: Resetting configuration After the measurement finishes successfully a window appears with measured milk parameters and adulterants if any detected (Figure 15, 17). If a substantial volume of unknown adulterant is detected - you will see ”Abnormal sample”.

Easiest way is to make PC as DHCP server with a small program called SmallDHCPServer.exe (files will be sent separately). Executing that program allows PC set IP (in same subnet) to Spectra. Initial IP of PC will be 192.168.10.10.

All of them convert necessary data (last measurement) in CSV file format. a) First of methods is with program called getData.exe. After start, enter IP of the Spectra and push GET button - last record will be downloaded in current directory with name last record.csv b) Second method is with HTTP request.

Page 29: Admin Menu
This menu helps us to do the calibration remotely. Use of this menu is rare - for example, when the Ekomilk Spectra is damaged and part of the infrared system needs to be replaced (the cuvette, the glass of the cuvette, measuring board, etc.). - Page 30 But strongly recommend to don’t touch them, unless you are not absolutely sure what you do and reference instrument is really exact. From drop-down menu select for which milk type you want to set correction, then click desired parameter, which you want to correct.

Send results FTP server Ekomilk Spectra can send results to FTP server. The results are stored in comma separated value (CSV) file with this header: • CP code - Collection Point Code of the analyzer. It serves as the ID. - Page 32 4. Send result - this step is the most important, because the ftp file is generated at the end of every shift and sending to your server, if Ekomilk Spectra is connected to the internet. If you don’t have internet connection, you can send files manual.

• Download data/result file - to download data/result file open Windows PowerShell (Command Prompt) and navigate to the directory where you want to download the data/result files. After that connect to Ekomilk Spectra and navigate to data/result directory. With command get followed by file name you will start download (for example: get 2019 10 25.txt). -
Page 36: Appendix 1 - Some Reason For Ekomilk Accuracy And Repeatability Deviations
Below are described some reasons that may worsen the accuracy and repeatability of the Ekomilk Spectra Analyzers measurement results. Some information about the way to avoid these problems is provided as well. 1. Aired milk - this is milk with a lot of tiny air bubbles inside. This air bubbles are very small and it takes long time - from one to more than 10 or even 20 hours for these air bubbles to get out of the milk. - Page 37 In this case it is recommended several dummy samples (with water or milk) to be made before the real samples are tested. 10. Wrong milk type tested - Ekomilk Spectra is factory calibrated for tree different kinds of milk in accordance with the customer request - cow, buffalo and mixed milk.

This is a full list of measurable ultrasound parameters. Possible, in some cases user don’t want to see all of them. If some parameter is disabled for displaying, it’s place in this packet will be filled with spaces (0x20).

Page 40: Appendix 3 - Troubleshooting
13 Appendix 3 - Troubleshooting 13.1 Filter clogging(infrared only) In case of air bubbles visible in the thin tubing entering the cuvette, the filter on the spout of the infrared module could be clogged. This is often the problem when that happens because the peristaltic pump cannot suck in enough sample and vacuum is created in the system. -
Page 41: Sticking Of Pump's Silicone Hose(Infrared And Ultrasound)
13.3 Sticking of pump’s silicone hose(infrared and ultrasound) If the Ekomilk Spectra has not been used for a long time or has not been cleaned, the pump hose may become stuck. Signs of this are, for example, if the pump is rotating but cannot suck milk or cleaning solution. - Page 42 4. Slowly pull out the plastic cover. 5. Remove the silicone hose from the pump and see where it stuck. 6. Then grasp it with two fingers and begin to massage it. 7. Once it has blown off you can start assembling it. When replacing the silicone hose, you can gently rotate the pump to make it easier to install.

Page 43: Maintenance
Note: Never subtract the cuvette, while the device is turn on. Note: If the cuvette is removed, the calibration may not be appropriate and the Ekomilk Spectra may will not measure correctly. The operation of cuvette ejecting or replacement should be performed by an authorized service or technician. - Page 44 3. When the cuvette is unlocked, pull it out. 4. The cuvette is released from the system, when unplugging the upper and lower hose from the nozzles.
- Page 45 5. Inserting the cuvette into the system. NOTE: When inserting the cuvette back in the analyzer, it is very important to take care of the direction of the hoses, help manually to ensure their proper direction and to avoid hose pinching and bending. 6.
