From Total Berry UK : We have received the first Softlab thank very much I would like to order another one please that is exactly the same From OGC, USA The softlab is the most objective device on the market. It is essentially our only choice. From Oregon, Blueberries Long story short, we absolutely thrilled with the machines. They are everything we expected and then some. We’ve been using them for a couple of weeks now and are completely comfortable using them.  Whenever anyone asks what I recommend, I can assure you that AGROSTA will the first words to come out of my mouth. From Ocean Spray, USA : Spent some time working with the Winterwood today. It is an ingenious machine. Setup was pretty straightforward From Ocean Spray, USA : First off I must say it is quite a versatile machine, it has done a good job of streamlining the process of both sizing and firmness testing thus far.  Furthermore, retests performed on random batches have so far come up nearly identical to the results of the first tests, which is a great sign.
From BBC, New Zealand : We would like to purchase one of these machines for firmness testing of Blueberries. We have a Firmtech, but have found it unreliable with its measurements

AGROSTA®Winterwood is an automatic machine for testing a batch of fruits or vegetables. It provides color, size and

firmness, as well as statistics, exportable to Excel

This laboratory instrument is provided with : - The software for Windows, compatible with all Windows versions (Vista, XP, 7,8,8.1,10) - 2 different turntables according to the type of fruits you want to test (Additional turntables are available as options) - The sensor head is pre-equipped with the size of tip corresponding to the type of fruits you want to test Agrosta®Winterwood dedicated to soft fruits with smooth skin (Durofel sensor head) : - The turntables have 32 cups for blueberries (4 different models of turntables according to blueberry size : Small, Normal, Big, Big+ covering from 10mm to 37mm diameter) - Please note that the winterwood machine is the only device in the world measuring blueberry firmness with a good accuracy - 20 Cups for cherries (2 models : big and small), cranberries, grapes, olives The machine comes with high precision Stepper motors, making 800 steps for 1mm movement (Precision 0.1mm), A main board coming from Italy, a Spectrophotometer (Colorimeter) board with infrared filter made in the USA Just place carefully your fruits on the turntable, place the turntable on the machine, and start a cycle from your computer.. All measurements are displayed in a chart that can be exported to Excel. Graphs are displayed, they can be exported as well

- The firmness

The firmness is determined by squeezing the fruit in the same manner a consumer would do with his fingers. It is determined through the durofel index with 2 different tips available (’10’ for apricot and tomato, ‘25’ for cherry and blueberry) The machine is provided with the tip according to the type of fruits you are going to test. Additional tips are available as option. the measurements are in Durofel index (from 0 to 100%) and grams per mm2. the Durofel unit is based on Shore A standard : It is the only reliable principle for measuring the firmness of fruits like blueberries or cherries

- The color measurement

VISIBLE RANGE : It is done as the fruit sequences through the machine on the turntable - The machine comes with a Spectrophotometer, which gives very intuitive measurement : The intensity of light reflected along the visible range, using 6 different wavelengths. Our color sensor comes from the Usa, and is a high quality device - We have added a small glass lens in order to facilitate fruit juice cleaning, and increase accuracy

- The size

The machine counts the number of steps the motor has to do in order to reach the fruit surface (400 steps for 1mm) - You have to parameter the initial size in the software, and Winterwood gives the fruit diameter at probe position. This is approximate, as it depends on the position of the fruit inside the cup of the turntable But it is very representative from a statistic point of vue

- Interchangeable trays

You just need a few seconds if you want to change the tray..

From Fresh Forward, Nederland : The spectrofotometer, I really like the output  Blueberries Company in South Africa : I appreciate the help and love the new machine From Agroservicios, Chile : The new machine works perfect so far

New in 2019 :

Agrosta engineering team makes continuous improvements : - Our Turntable firmness tester for fruits comes now with an improved design : Laser cutted plexiglass plates have been added in order to increase rigidity, and improve cleaning in some areas in contact with fruit juice - The texture analysis strategy has been improved, the sensor head is now touching the fruit first, going back, and then measuring at low speed. this increases measurement accuracy - Our turntable fruit firmness tester is now taking measurement at a speed of 80 Hz (80 measurements per second) instead of 10 Hz previously. As only the maximum pressure is recorded, the user cannot feel it, but the accuracy is improved - Our turntable fruit testing machine software has been updated, it became more intuitive and easier to use - Our huge experience in blueberry sorting technologies has driven to many small improvements as well - Cherry and tomato firmness testing have been improved - We have invested in 2 digital operated machining centers and one SLA 3D printer in order to produce high accuracy machine components - The mechanical, chemical and temperature resistance of the components of our turntable firmness tester have been improved : Use of plexiglass, epoxy resin and high temperature PLA plastic - Our Turntable fruits testing machine comes now with a spectrophotometer covered by a glass (Instead of plastic), that avoids scratches and improves sealing - In May, a Barcode scanner has been added, you can insert barcode references in the chart before exporting to Excel
US Department of Agriculture : We did receive the machine, it is so compact and sturdy! Very good engineering! we are really amazed with how close the size measurement is to our hand measurement. The averages are very good!  Thank you again for all of your support in getting us started. We are excited about using the Agrosta, we think it is a big advancement for our laboratory!
- New turntables : More rigidity, better color measurement - Our turntable machines come now with a BARCODE scanner, and the software adapted for BARCODE management, The price stays unchanged

AGROSTA®Winterwood is an automatic machine for testing a batch of fruits or

vegetables. It provides firmness (using a Durofel head, measurements 0 to 100%) and

size - An optional colorimeter is proposed (Placed under the turntable)

Agrosta Winterwood is dedicated to soft fruits (Like Tomatoes, Grapes, Plums..) and berries (Blueberry, Cherry, Apricot, Cranberry..) Those fruits can be tested using the “Firmtech” principle as well with our Wonderful machine But there are many advantages at using the Durofel measurement principle for soft fruits and Berries : - The accuracy is far better : - The effect on measurement of irregularities on the surface of the fruit is very attenuated - Mechanical inaccuracies are also reduced by the use of the abutment used in Durofel measurement - Durofel is a proven principle based on Shore A standard (Shore norm is dedicated to soft materials, rubber and foams) - Some publications on Durofel principle : - STRAWBERRY (Resistance to bruising) : 2019 M.

The size is provided in mm and can be calibrated by the user The optional colorimeter provides a raw value for the following colors : Purple / Blue / Green / Yellow / Orange / Red. The maximum value is obtained for a pure white and the minimum for a pure black. for some fruits (like cherries), only one color (red) will provide very interesting data - In the case of cherry, the red value will decrease with maturity The software for Windows, compatible with all Windows versions (Vista, XP, 7,8,8.1,10), comes with a light version of Excel (So the user does not need Office on his/her computer) The tables available : - 4 different tables for blueberries (Small / Normal / Big / Big+) with 32 cups (measurement of 32 fruits within 2minutes 40 seconds if no colorimeter) - 3 different tables for cherries (Small / Normal / Big) Big can be used for apricot or cherry tomato as well - 1 Table for grapes - 1 Table for peach / nectarine The table can be changed within a few seconds The machine comes with the cables, power plug according to your country, software for windows, set of tip protections, manual and certificate of conformity and the tables you have ordered
