Specialising in industrial refrigeration and the\u00a0food cultivation industry since its creation in\u00a01997, FCV works principally to support the endive\u00a0production market (80%), but also works\u00a0with potato and fruit producers in northern\u00a0France. In addition, FCV is recognised in the\u00a0market for its vacuum cooling cells.\u00a0Pascal Hollocou trained as an engineer and was\u00a0a director at Alcatel Lucent before he launched\u00a0his new venture by purchasing FCV in 2010,\u00a0with the aim of being his own boss and exploring\u00a0a new profession: refrigeration. The company\u00a0is now a successful operation, with 9 employees\u00a0and a turnover of 1.85 million euros.<\/p>\n

The cultivation of endives (also known as chicory\u00a0or chicon) is a labour-intensive process. The\u00a0endive does not exist in a natural state. It is the\u00a0result of a forcing process developed around\u00a0the middle of the 19th century. To produce the\u00a0white leaves, the plants need to be grown in\u00a0total darkness. Endive production takes place\u00a0in 5 stages (see below) and\u00a0requires specific expertise from both the producer\u00a0and the refrigeration specialist.
\nD\u00e9sir Nature SARL has opted for an\u00a0ecological process\u00a0<\/strong><\/p>\n

Henri Tr\u00e9vaux, an affiliate member of the\u00a0Lefebvre family operation based in Peronne,\u00a0branched out into organic cultivation five years\u00a0ago. The time was right for such a change and\u00a0the endive producer also now has the facility\u00a0to source organically grown root crops locally.\u00a0In 2014, the production of \u201cD\u00e9sir nature\u201d organic\u00a0endives required the construction of a new\u00a0endive cultivation facility to meet the organic\u00a0farming criteria for AB accreditation. Henri\u00a0Tr\u00e9vaux collaborated with FCV to design the\u00a0industrial refrigeration processes required for\u00a0endive cultivation.\u00a0\u201cRefrigeration is crucial, particularly\u00a0for conserving endives in cold rooms\u00a0and growing them in forcing rooms\u201d, Pascal\u00a0Hollocou reminds us.<\/p>\n

Industrial process specifications<\/strong><\/p>\n

Once they have been harvested from the fields,\u00a0the endives need to be stored on pallets in\u00a0cold rooms, in order to preserve their roots.\u00a0The aim is to cool the heart of the endives to\u00a0around 0\u00b0C as quickly as possible from the\u00a0moment they are introduced, and to ensure air\u00a0circulation between each pallet to avoid them\u00a0drying out. Then, as required, the endives are\u00a0removed and placed in the development room.<\/p>\n

The endive grows to maturity over three weeks\u00a0– this is the forcing process. The ambient temperature\u00a0needs to be between 12\u00b0C and 22\u00b0C,\u00a0depending on the stage of development. The\u00a0room also needs an irrigation system for the\u00a0forcing trays, allowing water to reach each\u00a0stack of crates at a temperature of between\u00a08\u00b0C and 18\u00b0C. It should also be noted that this\u00a0living product gives off heat.<\/p>\n

\"FCV<\/p>\n

FCV choose\u00a0Greenway\u00ae Neo<\/strong><\/p>\n

FCV\u2019s process is to guide their customers,\u00a0where possible, towards a glycolated water\u00a0system, in order to minimise the quantity of refrigerant\u00a0in the installation, in line with evolving\u00a0regulations.\u00a0Pascal Hollocou discovered Greenway\u00aeNeo<\/a>\u00a0at technical meetings organised by Climalife\u00a0in northern France, and offered his customer\u00a0this vegetable based secondary refrigerant,\u00a0manufactured from 1-3 propanediol rather than\u00a0traditional\u00a0fluids derived from petroleum, to\u00a0remain\u00a0faithful to his ecological process.The decision was taken immediately,<\/em>\u00a0Henri\u00a0Tr\u00e9vaux points out. Although it wasn\u2019t stipulated\u00a0in the \u201cAgriculture Biologique\u201d label specifications,\u00a0in terms of organic image, it was important.<\/em><\/p>\n

Proven experience for a complex and\u00a0consistent installation<\/strong><\/p>\n

To meet the specifications and remain within\u00a0the budget, FCV used its accumulated experience\u00a0in the field to install all of the refrigeration,\u00a0ventilation and irrigation equipment.<\/p>\n

FCV\u00a0equipped the cold room with an MTA Aries\u00a0Tech chilled water system with a cooling capacity\u00a0of 116 kW.\u00a0Recycled heat from this externally located\u00a0group is used to produce hot water to defrost\u00a0the double-flux Profroid Duo 60 evaporators.<\/p>\n

For the forcing room, FCV was required to heat\u00a0and cool water and air. Another MTA chilled\u00a0water system with a cooling capacity of 93 kW\u00a0was installed. For the heat, an MTA Hocean geothermal\u00a0heat pump drawing on groundwater with a heating capacity of 86 kW was installed.<\/p>\n

This heat pump heats a facility with a surface\u00a0area of 25,000 m\u00b2.\u00a0The volume of Greenway\u00aeNeo<\/a>\u00a0secondary refrigerant\u00a0used is 1,600 Litres for all the circuits.\u00a0Each item of equipment, where possible, is fitted\u00a0with frequency converters in order to optimise\u00a0the installation\u2019s energy efficiency.\u00a0Frequency converters are rarely used in the\u00a0<\/em>agricultural industry<\/em>, the refrigeration technician\u00a0reminds us. This is an innovation that\u00a0<\/em>allows us to reduce operating costs, which are\u00a0<\/em>crucial in endive production facilities such as\u00a0<\/em>these.<\/em><\/p>\n

Endive cultivation,\u00a0a specialised technology<\/strong>
\nIn order to retain its whiteness, the endive needs to be grown in the dark, in a warm\u00a0and humid atmosphere. The 5 stages of endive production are:<\/em><\/p>\n\n\n\n\n
\"\"<\/td>\n\"conservation<\/td>\n\u00a0\"pousse<\/td>\n\"cassage<\/td>\n\u00a0\"\u00e9pluchage<\/td>\n<\/tr>\n
1. Seeding<\/strong><\/p>\n

To begin with, the seeds are sown in the fields in May. After 5 or 6 months, the endive roots develop \u00a0in the ground, filling themselves with nutritious elements. They are then uprooted and harvested in November.<\/td>\n

\u00a02.\u00a0Conservation of endive roots<\/strong><\/p>\n

In order to spread \u00a0production over time, roots \u00a0are placed into large wooden crates then kept in a cold room for a period of between 8 days and 8 months.<\/td>\n

\u00a03. Growing the endives<\/strong><\/p>\n

For the root to produce the endive, it is placed in damp, dark and warm \u00a0conditions, in a facility known as the forcing room<\/strong>. The roots release their nutrients, allowing the endive to grow over a period of 21 days.<\/td>\n

\u00a04.\u00a0Breaking<\/strong><\/p>\n

Once the endive reaches maturity, it is separated from the root (broken).<\/td>\n

5. Peeling<\/strong><\/p>\n

The endives are peeled, sorted and packaged in sachets or cardboard boxes.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
