The Stamford Bridge side have no fewer than 24 players on loan at the moment - with several on temporary deals at fellow Premier League clubs.
Victor Moses joined Liverpool on transfer deadline day, while Romelu Lukaku will spend the season at Everton.
And Chelsea have six players on loan at Dutch club Vitesse Arnhem, which has provoked controversy in the Eredivisie.
Sam Hutchinson, Christian Atsu, Gael Kakuta, Cristian Cuevas, Lucas Piazon and Patrick van Aanholt have all joined Vitesse this summer.
And a number of Eredivisie clubs have registered their displeasure at the arrangement, including Nijmegen EC director Carlos Aalbers.
Chelsea have a good working relationship with Vitesse - Roman Abramovich and Vitesse's owner Merab Jordania are business acquaintances - and the Stamford Bridge club signed Vitesse's most promising young player, Marco van Ginkel, over the summer.
But Emenalo has defended Chelsea's loan policy, insisting the club uses it as a way of guaranteeing its top young stars first-team football.
"We are trying to find a way because given Financial Fair Play stipulations we need to recruit young and we also need to have a reservoir of talent that we develop," he told the club's official website.
"We identified that for young players, the ages of 18 to 21 is the most difficult as they wonder if they are good enough for the Chelsea first team and what is next for them.
"We felt it is better for them at that age to go on loan to somewhere where they get visibility and good competition. For psychological and physical reasons that is the best thing to do at that age.
"They test themselves and they feel good about competing at a higher level, and it also gives us a chance to evaluate them and know if they are ready to come back.
"The loan process at Chelsea has become very professional and a good deal of thought has gone into it.
"We don't send players out because we are trying to recover some money, we send them because we want them to play and develop and we want to monitor them.
"We have a system in place that means we keep a close eye on them and the manager knows exactly what is happening at all times."
Chelsea have had success in the recent past loaning players out. Belgian international Kevin De Bruyne spent last season at Werder Bremen where he impressed, and he's returned to play an important part in Jose Mourinho's first team plans so far this term.
